Early life

Williams was born in Saginaw, Michigan, to Richard Williams and Oracene Price, and is the youngest of Price's five daughters: half-sisters Yetunde, Lyndrea and Isha Price, and full sister Venus. When the children were young, the family moved to Compton, California, where Williams started playing tennis at the age of three. Her father, Richard, home-schooled Serena and her sister Venus. While he and subsequently her mother, Oracene, have been the official coaches, other mentors who helped her learn the game included Richard Williams in Compton who would go on to found The Venus and Serena Williams Tennis/Tutorial Academy.

Williams' family moved from Compton to West Palm Beach, Florida, when she was nine so that she could attend the tennis academy of Rick Macci, who would provide additional coaching. Macci spotted the exceptional talents of the sisters. He did not always agree with Williams' father, but respected that "he treated his daughters like kids, allowed them to be little girls". Richard stopped sending his daughters to national junior tennis tournaments when Williams was 10, since he wanted them to take it slow and focus on school work. Another factor was racial, as he had heard white parents talk about the Williams sisters in a derogatory manner during tournaments. At that time, Williams had a 46-3 record on the United States Tennis Association junior tour and was ranked No. 1 among under-10 players in Florida. In 1995, when Williams was in the ninth grade, her father pulled his daughters out of Macci's academy and, from then on, took over all coaching at their home. When asked in 2000 whether having followed the normal path of playing regularly on the junior circuit would have been beneficial, Williams responded: "Everyone does different things. I think for Venus and I, we just attempted a different road, and it worked for us."

Playing style

Williams is primarily a baseline player and her game is built around taking immediate control of rallies with her powerful and consistent serve, return of serve, and forceful groundstrokes from both her forehand and backhand swings. Williams' forehand is considered to be among the most powerful shots in the women's game as is her double-handed backhand. Williams strikes her backhand groundstroke using an open stance, and uses the same open stance for her forehand. Williams' aggressive play, a "high risk" style, is balanced in part by her serve, which most say is the greatest in women's tennis history. She consistently projects great pace and placement with her serves and in the 2013 Australian Open, she had a peak serve speed of 128.6 mph (207.0 km/h) which is the third fastest all-time among female players (only Venus's 129 mph and Sabine Lisicki's 131 mph recorded speeds are faster). What makes her serve even more deadly is her ball placement and her ability to consistently place powerful shots with great accuracy. At the 2012 Wimbledon Championships, she hit a women's tournament record of 102 aces which was more than any of the men hit during the two weeks. Williams also possesses a very solid and powerful overhead. Although many think of Williams as only an offensive player, she also plays a strong defensive game. She has stated that her favorite surface is clay because it gives her extra time to set up her shot.

She has won three Grand Slam singles titles after saving match points, (2003 Australian Open versus Kim Clijsters, 2005 Australian Open versus Maria Sharapova, and 2009 Wimbledon versus Elena Dementieva), more than any other player in history, male or female. She also came back from a 3-5 deficit in the third set against Kim Clijsters in the 1999 US Open and went on to win her first Grand Slam singles title. In the 2012 US Open final against Victoria Azarenka, she was down 3-5 in the third set and found herself two points away from losing the match. Williams then proceeded to win the next 4 games and defeated Azarenka. In recent years, Williams has shown an ability to serve aces at critical moments. One of these instances was the 2013 French Open final, where in the last game of the match, she fired three aces, including one which clocked at 123 mph (198 km/h) on match point. In the semi-finals of the 2015 French Open, Williams was ill and barely able to walk during changeovers, yet beat her opponent, Timea Bacsinszky, 6-0 in the third set. Another improbable win occurred in the third round of the 2015 Wimbledon Championships, when she recovered from two breaks of service in the third set to defeat Great Britain's No. 1 female player, Heather Watson. Williams has bounced back from a set down to win in 33 Grand Slam matches.

Williams suffered her first ever loss in the opening round of a Grand Slam tournament at the French Open against Virginie Razzano. Williams notched up a 33-1 record for the second half of the season winning five titles in the process. Williams won her fifth Wimbledon singles title, her fourteenth major title; setting a serving record of 24 aces by a female in a match as well as having the most aces, male or female, during the tournament (102). Williams returned to America to successfully defend her title in Stanford beating Coco Vandeweghe in the final. Serena then returned to Wimbledon to represent her country at the Olympic Games where she won gold. Williams undefeated streak ended with a loss in Cincinnati to Angelique Kerber. In New York City, Williams went on to win her fourth US Open singles title and her 15th career major title overall beating Azarenka in the final. Williams ended the season by competing at the WTA Championships and went undefeated throughout the tournament to win the event for her third title. Serena Williams was voted WTA Player of the Year for the fourth time. Based on her brilliant show in 2012, Serena was also named International Tennis Federation World Champion. Williams also returned to doubles competitions with Venus; in the pair's first tournament since 2010 Wimbledon, they claimed their fifth Wimbledon doubles title and the 13th grand slam doubles title. The pair successfully defended their Olympic doubles title which meant that they became the only tennis players to win four gold medals.

Williams' first tournament of the 2013 season was in Brisbane, where she won the title without dropping a set. Williams was upset in the quarterfinals of the 2013 Australian Open by fellow American player Sloane Stephens. By virtue of defeating Petra Kvitová in Doha, Williams returned to the world No. 1 position for the sixth time in her career and became the oldest woman in the Open Era to hold the ranking. Williams went on to lose to Victoria Azarenka in the final. In the Miami final, Williams lost a set to Maria Sharapova for the first time since 2008. However, this setback did not stop Williams who recorded her seventieth come-from-behind win. The win made Williams a six-time champion in Miami breaking the record she held with Steffi Graf and became only the fourth woman in the open era to have won a tournament at least six times. Williams successfully defended her Charleston title, winning it for the third time overall. Williams won her fiftieth career singles title in Madrid, defeating Sharapova in the final. Williams then played Rome, where she won the title without dropping a set, defeating Victoria Azarenka in the final to take her second title. Williams only dropped ten games in reaching the quarterfinals at Roland Garros. There, she played Svetlana Kuznetsova and lost her first set of the tournament. In the semi final Williams only lost one game when she defeated Sara Errani, something seven-time French Open champion Chris Evert described as the finest female performance on clay she had ever seen. Williams defeated Sharapova to claim her second Roland Garros title, her sixteenth grand slam tournament title overall. She became the fourth woman in the Open era after Martina Navratilova, Chris Evert and Steffi Graf to win each Grand Slam tournament title on at least two occasions. At the 2013 Wimbledon Championships, she advanced easily to the fourth round before being upset by eventual finalist Sabine Lisicki in three sets. After Wimbledon, Williams won the Swedish Open by defeating Johanna Larsson in the final, the tournament win marked the first occasion that she had won an International level title. By winning the tournament this meant that Williams had managed to be undefeated on clay during the season.

Williams won her third Rogers Cup title in Toronto beating Sorana Cîrstea in the final. Williams reached the final of the Western & Southern Open for the first time but lost to Azarenka. At the 2013 US Open, Williams began as the top seed and defending champion. She reached the final—a rematch of the 2012 final against Azarenka—and won in three sets, capturing her 17th Grand Slam singles title. Williams became the oldest US Open champion in the Open Era and pushed her career prize money past $50 million. After the US Open, Williams headed to Beijing where she beat Jelena Janković to win the China Open for her 10th title of 2013. Williams went through the WTA championships undefeated winning the final against Li Na, to become the first person to defend the title since Justine Henin in 2007. Williams won her eleventh title of the year becoming the eighth player to win eleven tournaments or more in a year and the first since Martina Hingis in 1997. Additionally, Williams became the oldest person to win the WTA Championships and the fourth player to win the event four times or more. By winning the championship, Williams became the first woman to win more than ten million dollars in a season and with her total of $12,385,572, only Rafael Nadal, in 2013 and Novak Djokovic, in 2011, 2012 and 2013, have earned more money in a single season. Williams finished as the year end world No. 1 for the third time, becoming the oldest No. 1 player in WTA history. She was also named the 2013 ITF World Champion, the fourth time that she has been given the World Champion's crown. Williams received two prizes at the 2013 ESPY Awards. Williams won Best Female Athlete and Best Female Tennis Player. Williams is just the fourth person to win Best Female Athlete on two occasions and she won Best Female Tennis player for a record sixth time. In late December 2013, Williams capped off her year by receiving the Associated Press (AP) 2013 Female Athlete of the Year award, her third AP award after 2002 and 2009. Only two women, Chris Evert and Babe Didrikson, have been chosen more often as AP Athlete of the Year since the annual awards were first handed out in 1931.

2014-15: Second "Serena Slam"

Main articles: 2014 and 2015 Serena Williams tennis season

Williams defended her title at the Brisbane International by defeating world No. 2 Victoria Azarenka in the final. At the Australian Open she ended up losing to former world No. 1 Ana Ivanovic in the fourth round, later revealing that she had considered withdrawing from the tournament even before her third round match because of a back injury. At the 2014 Dubai Tennis Championships, Williams lost her semi-final match to Alizé Cornet in straight sets. Williams next headed to the Miami Open where she won her record seventh title with a straight-sets victory over world No. 2 Li Na. Serena lost to Jana Čepelová in the second round of the Family Circle Cup. She made it to the quarterfinals at the Mutua Madrid Open before withdrawing with a left thigh injury. Williams won her third title of the season at the 2014 Internazionali BNL d'Italia. She was then handed the worst loss of her Grand Slam tournament career by Garbiñe Muguruza at the second round of the 2014 French Open, who defeated Serena losing just 4 games in two sets. Alizé Cornet defeated Williams for the second time in the year in the third round of Wimbledon, thus handing Serena her earliest Wimbledon exit since 2005. Serena was then forced to withdraw from the doubles event alongside sister Venus Williams while trailing 0-3 in the second round. A disoriented Serena hit 4 consecutive doubles faults and was having trouble with both her ball toss and movement before being removed from what has been described as one of the most unusual scenes ever seen in tennis.

Williams rebounded by winning 19 out of her next 20 matches (losing only to sister Venus in the semifinals of the Rogers Cup). This streak include titles at the Bank of the West Classic as well as her first Western & Southern Open title and her third consecutive and sixth overall US Open singles title which she won without having dropped a set. With this victory Serena tied Chris Evert for most singles titles won by a woman at the US Open in the Open Era. Williams also tied Evert and Martina Navratilova's 18 major singles titles won in the Open Era. By virtue of having won both the US Open and the US Open Series, Williams collected $4,000,000 - the biggest payday in tennis history. At the Wuhan Open a viral illness forced her to retire while up a break in the first set against Alizé Cornet. Cornet thus became the first woman since Justine Henin in 2007 to record three victories over Williams in one year. At the China Open Williams retired prior to her quarterfinal match versus Samantha Stosur. At the 2014 WTA Finals in Singapore Serena advanced to the final for the third consecutive year despite having equaled her career worst loss in her second round robin match versus Simona Halep. Williams won her fifth WTA Finals title by avenging her loss to Halep in the championship match for her seventh title of the year. Serena finished the year ranked world No. 1 for the fourth time in her career. She held the No. 1 ranking for the entire calendar year, a feat not accomplished since Steffi Graf in 1996. She was also voted WTA Player of the Year and ITF World Champion for the third consecutive year (sixth year overall).

Williams began the 2015 season by representing the United States alongside John Isner at the Hopman Cup. The American pair lost the final to the Poland. At the Australian Open Williams defeated Maria Sharapova of Russia for the sixteenth consecutive time to claim her 6th Australian Open singles title and 19th career Grand Slam singles title, winning the title on her third match point in the second set. With this victory Williams surpassed both Chris Evert and Martina Navratilova for second most Grand Slam singles titles won in the Open Era. The title was also her sixth Grand Slam singles title since turning 30 years of age, three more than the next closest to do so (Margaret Court, Martina Navratilova with three each). She is the only player in history to win all four majors at least once after having turned 30. The following weekend, Serena and sister Venus traveled to Buenos Aires, Argentina to face Argentina in a World Group II tie for Fed Cup. She played and won her only match against María Irigoyen to help Team USA to a 4-1 win over Argentina. Williams announced that she would be competing at the Indian Wells Masters ending her 14-year boycott of the event. Upon her return Williams received a standing ovation from the crowd and won her first match in straight sets. She reached the semifinals, where she was due to face world No. 3 Simona Halep for a place in the final, but was forced to withdraw because of a knee injury. By virtue of having defeated Sabine Lisicki in the quarterfinals of the Miami Open, Serena became only the eighth woman in the Open Era to record 700 match wins in her career. This also made her one of only three active players to have won 700 or more matches in singles, the others being Roger Federer and Rafael Nadal. In the semifinals she won against Halep to advance to her tenth final at the event, where she won a record eighth title and extended her winning streak to 21 matches by beating Carla Suárez Navarro.

As preparation for the clay court season (and to ensure her eligibility for the 2016 Summer Olympics), Williams travelled to Brindisi, Italy, to face Italy's team for a place in the Fed Cup's World Group. Williams lost the decisive doubles match alongside Alison Riske to Sara Errani and Flavia Pennetta and as a result the United States were relegated to World Group II. It was Williams' first loss in the Fed Cup. However, she maintained her perfect record in singles by defeating Camila Giorgi and Errani. The week of April 20 marked Serena's 114th consecutive week ranked world No. 1, the third-longest run in WTA history behind Steffi Graf's 186 weeks and Martina Navratilova's 156. Williams suffered her first defeat of the season in the semifinals of the Mutua Madrid Open to world No. 4 Petra Kvitová. This loss ended a 27 match winning streak for Williams as well as a 50 match winning streak at Premier Mandatory events and also a 19 match winning streak at the particular event. Williams played one match at the Internazionali BNL d'Italia before withdrawing from the tournament with an elbow injury. By virtue of having defeated Victoria Azarenka in the third round of the French Open, Williams became the first woman in the Open Era to win 50 matches at all four of the majors. Williams then defeated Sloane Stephens to reach her 40th Grand Slam singles quarterfinal. Serena won her next match easily, but had to come back from a set down in the semifinals versus Timea Bacsinszky for the fourth time in five matches to reach the final. She would go on to defeat Lucie Šafářová from the Czech Republic in three sets to win her 3rd French Open and 20th Grand Slam singles title. The win made her only the third person in history to win each major at least three times, joining Margaret Court and Steffi Graf. She's the first player to win three straight majors since she did it herself during the Serena Slam. She also became the first player to win the Australian-French Open double since Jennifer Capriati in 2001.

Williams completed her second "Serena Slam" (winning all four majors in a row) by winning the 2015 Wimbledon Championships - her 6th Wimbledon and 21st Grand Slam singles title overall. Her path to victory at Wimbledon was particularly challenging. She was down a double break in the third round versus Heather Watson and two points from defeat twice before rallying for the win and becoming the first player to qualify for the WTA Finals (the earliest that a player had qualified since the event switched to the round-robin format in 2003). Williams then defeated three former number 1 players - Venus Williams, Victoria Azarenka and Maria Sharapova—in succession to advance to the final. Awaiting her there was 21-year-old Garbiñe Muguruza, who had previously handed Williams the worst Grand Slam tournament defeat of her career at the 2014 French Open. Williams defeated Muguruza in a tight two-setter. The victory made her the oldest woman in the Open Era to win a grand slam singles title, in addition of having the distinction of being the oldest ladies' singles champion of all of the grand slam tournaments. It also was her eighth consecutive victory in Grand Slam singles finals appearances, breaking Steffi Graf's Open Era record of seven from 1995 through 1999 and, on the men's side, tying Pete Sampras' Open Era record of eight from 1995 through 2000. Her 21 major singles titles equaled the tally of the rest of the women's tour, combined. The week of July 13 marked the first time in WTA history that the No. 1 player had more than twice as many points as No. 2. Following her win at Wimbledon, Williams was awarded with her 7th ESPY for Best Female Tennis Player.

Williams played one match at the Swedish Open in Båstad before withdrawing with an elbow injury. She was the defending champion at the Bank of the West Classic but withdrew from the tournament in order for her elbow to get better. Williams had her 19 match winning streak ended by 18-year-old Swiss Belinda Bencic, the world No. 20, in three tight sets in the semifinals of the Canadian Open. It was her second defeat of the year and first on hard courts since the 2014 WTA Finals. The next week Williams defended her title at the Western & Southern Open with a straight sets victory over world No. 3 Simona Halep for her 69th WTA title, breaking a tie with Evonne Goolagong for standalone fifth-most WTA titles won. Williams' attempt at capturing the "Grand Slam" (winning all four majors in a calendar year) came to an end in the semifinals of the US Open, where she lost to Roberta Vinci in three sets. The loss has been described by some as one of the biggest upsets in tennis history. Nonetheless, Williams secured the year-end No. 1 ranking with her results at the tournament. On October 1, Williams called an end to her season, stating that she had been injured for most of the year and wanted to address her fitness issues. Prior to the announcement, coach Patrick Mouratoglou hinted that Williams might not play again in 2015 due to a lack of motivation and disappointment following her loss at the Open. On October 5, Williams surpassed Chris Evert for third-most weeks ranked world No. 1. Williams held the No. 1 ranking the entire season for the second consecutive year, finishing there for the fifth time in her career. She was voted WTA Player of the Year for the seventh time in her career. On December 14, Sports Illustrated announced Williams as their Sportsperson of the Year. She thus became the third solo woman, and first since 1983, to receive the award. Williams was also named ITF World Champion for the sixth time in her career. Soon after, it was announced that she was voted Female Athlete of the Year by the Associated Press for the fourth time.

2016-present

Main article: 2016 Serena Williams tennis season

Williams withdrew from the Hopman Cup after retiring from her singles match against Australia Gold with inflammation of her left knee. Her next tournament was the Australian Open, where she was the No. 1 seed and defending champion. She reached the final without dropping a set, including wins over No. 5 Maria Sharapova and No. 4 Agnieszka Radwanska, and faced first time Slam finalist Angelique Kerber. She was considered the heavy favourite to win the title, as she never lost in an Australian Open final or semifinals. She also dominated the head to head against Kerber, losing only once in six meetings and did not lose a set to her in four years. However,she lost in three sets and allowed Kerber to win her first Grand Slam title. This marked Williams' first ever loss in the final of the Australian Open, as well as her first three-set loss in the final of a Grand Slam. She had previously been 6-0 and 8-0 respectively.

The week of February 15 marked Serena's 157th consecutive week ranked world No. 1, passing Martina Navratilova's mark of 156 to have the second-longest run in WTA history behind Steffi Graf's 186.

She competed in Indian Wells as the No. 1 seed. She reached her first final here since winning in 2001 and before boycotting the event, by defeating Simona Halep in the quarterfinals and Agnieszka Radwanska in the semifinals and did not drop a set in all her five matches. However, she was upset by No. 13 seed Victoria Azarenka, whom she defeated the last five times they met, in straight sets. This marked the first time since 2004 which Williams lost two consecutive finals.

She next played the Miami Open as the defending champion. She lost in the fourth round to Svetlana Kuznetsova. This marked her first loss here since 2012 and ended her 20 match winning streak in Miami. This was also her earliest exit here since 2000, where she lost in the same round. During the clay court swing, Serena withdrew from Madrid but entered in Rome. She beat Anna-Lena Friedsam and Christina McHale to progress to the quarterfinals where she played Miami finalist Svetlana Kuznetsova. Williams had lost their previous meeting in Miami in three sets but dominated Kuznetsova, dropping only two games. She then went on to beat Irina-Camelia Begu and Madison Keys to win her 70th career WTA title and first of the year.

Rivalries

Serena vs. Venus

Main article: Williams sisters rivalry

Williams has played older sister Venus in 27 professional matches since 1998. Overall, Serena is 16-11 against her sister. Serena has played Venus 14 times in Grand Slam singles tournaments and 13 times in other tournaments (including 11 finals). They have met in eight Grand Slam tournament finals, with Serena winning six times. Beginning with the 2002 French Open, they played each other in four consecutive Grand Slam singles finals, which was the first time in the open era that the same two players had contested four consecutive major finals.

Williams vs. Hingis

Main article: Hingis-S. Williams rivalry

Williams leads series 7-6. One of Williams' first rivalries was with Martina Hingis, who turned pro less than one year before her (Hingis in October 1994, Williams in 1995) They first played each other at the 1998 Miami Open where Hingis won in three sets. All but one of their matches was played on a hard court with the exception being a contest on clay in Rome 1999, which Hingis won in straight sets. Their last match took place at the 2002 Miami Open with Williams winning for the loss of just four games. Hingis was forced to briefly leave the sport citing ankle injuries.

Williams vs. Capriati

Williams leads series 10-7. Once considered one of the best rivalries in women's tennis, the competition between Williams and Capriati was stiff with 12 out of their 17 meetings going to three sets. The rivalry, starting in 1999, started off one sided with Capriati winning four of their first five matches. Serena would then go on to win the next eight. Williams and Capriati played with similar styles, both known for using their power and athleticism to gain quick advantages in points.

Williams vs. Henin

Main article: Henin-S. Williams rivalry

Williams leads series 8-6. Henin and Williams met 14 times, 5 of which were in tournament finals. In grand slams they have faced each other 7 times with Justine leading 4-3. Opposite personalities and styles of play are often cited as what made their rivalry entertaining. In the semifinals of the 2003 French Open, when at 4-2, 30-0 on Williams' serve in the third set, Henin raised her hand to indicate she was not ready to receive and Williams then put her serve into the net. The umpire did not see Henin raise her hand and thus did not allow Williams a first serve. Williams lost the game and would go on to lose the match. Their last match took place in the final of the 2010 Australian Open where Williams won in three sets, earning her 12th Grand Slam title.

Match controversies

Accusations of match fixing

When the Williams sisters both entered the top ten and started meeting in tournaments, unsubstantiated rumors of match fixing started to circulate. John McEnroe, while commenting on the 2000 Wimbledon semifinal between the two sisters, said that "Serena may not be allowed to win. Richard may have something to say about this." Elena Dementieva, a fellow professional player, said during a post match interview after losing to Venus at the Indian Wells quarterfinals in 2001, that Richard Williams decided the results between the two sisters.

2001 Indian Wells

After injuring herself in the quarterfinal match against Dementieva, Venus Williams defaulted to Serena in the semifinals. Although Venus told the tournament official hours beforehand that she would have to default, the official word was not given until 10 minutes before the scheduled start (in the hopes that Venus would change her mind), angering fans who had come to see the match. Consequently, during the final against Kim Clijsters two days later, the spectators jeered Serena from when she first took the court for warm-up through the final trophy presentation including cheering double faults and errors with no intervention from the tournament officials. At the Ericsson Open the following week, Richard Williams said racist comments were made to him in the stands, and the tournament director refused to offer Serena an apology for how she was treated. As a result, neither sister played the tournament even though since 2009 it had become a mandatory stop on the WTA tour. In 2015, Serena decided to end her 14-year boycott and entered the tournament.

2004 US Open

In her 2004 U.S. Open quarterfinal match against Jennifer Capriati, an overrule was made by chair umpire Mariana Alves in Capriati's favor, even though later video review showed this to be an error (as Williams' shot was inside the court). There were calls that incorrectly went against Williams during the match, including late in the third set which prevented her from rallying from a break down. Williams attempted to argue a couple of calls, but was not successful. Capriati won the match, but tournament officials dismissed the umpire from the tournament, and she was suspended. The controversy renewed calls for the adoption of technology like the MacCam and Hawk-Eye systems.

2009 US Open

In 2009, Williams was again noted for her on-court behavior, this time a match against Kim Clijsters in the 2009 U.S. Open semifinal round. At the end of the first set, Williams slammed her racquet on the court in frustration over losing the set. She was given a warning, with a potential second violation carrying a one-point penalty. While trailing 4-6, 5-6, 15-30, Williams' second serve was called a foot fault, resulting in two match points for Clijsters. Williams gestured with her racquet to the lineswoman who had made the call and yelled at her, with profanities and a threat to shove a tennis ball down the lineswoman's throat. During the subsequent on-court conference between the chair umpire, the lineswoman, US Open officials, and Williams, a television microphone picked up Williams saying to the lineswoman, "I didn't say I would kill you! Are you serious?" The incident resulted in Williams being penalized a point for unsportsmanlike conduct‍—‌necessitated by the earlier warning for racquet abuse‍—‌meaning Clijsters won the match 6-4, 7-5. The following day, Williams was issued the maximum permissible on-site fine of $10,000 (plus $500 for racquet abuse). After further investigation, the Grand Slam Committee in November 2009 fined her $175,000 in lieu of suspending her from the 2010 US Open or other Grand Slam events. They also placed her on a two-year probation, so if Williams committed another offense in the following two years at a Grand Slam tournament, she would be suspended from participating in the following US Open. If she committed no offenses in the next two years, her fine would be reduced to $82,500. Williams initially refused to apologize for her outburst, both in her post-match press conference and in an official statement released the following day. She eventually apologized stating "I just really wanted to apologize sincerely, because I'm a very prideful person and I'm a very intense person and a very emotional person", and "I wanted to offer my sincere apologies to anyone that I may have offended." She said she had been humbled by the experience.

2011 US Open

In the final of the 2011 U.S. Open against Samantha Stosur, Williams again generated controversy. After shouting "Come on!" as the Australian attempted to return a forehand Williams believed to be a winner, chair umpire Eva Asderaki awarded the point to Stosur based on the USTA's deliberate hindrance rule, which states, "If a player commits any act which hinders his opponent in making a stroke, then, if this is deliberate, he shall lose the point or if involuntary, the point shall be replayed." As the point was 30-40 on Williams' serve, the penalty gave the break of serve to Stosur. Williams became angry with the chair umpire and made several gestures and unflattering comments toward her during the next changeover, including telling Asderaki that if she ever saw the umpire coming toward her, she should "look the other way". Williams initially gained momentum in the set following the penalty, breaking back in the next game, but eventually flagged and lost the match, 6-2, 6-3. At the end of the match, she declined to offer the customary handshake to Asderaki. Williams mentioned the incident in her post-match speech as the tournament runner-up, claiming, "I hit a winner, but I guess it didn't count", but added, "It wouldn't have mattered in the end. Sam played really well." A writer for ESPN suggested that Williams could avoid being found to have violated the terms of the "probation" on which she was placed following her 2009 outburst, as she did not appear to have used profanity in addressing Asderaki during the match. In the end, Williams was fined $2,000 and was not barred from competing in the 2012 US Open because "...Williams' conduct, while verbally abusive, not rise to the level of a major offence under the Grand Slam code of conduct."

Off-court activities

Equipment and endorsements

In the early 2000s, Williams wore Puma apparel and footwear on court. She used Wilson Hammer 6.4 Stretch Power Holes racquet. Today, she is endorsed by Nike and uses the Wilson Blade 104.

Williams also has endorsement deals with Gatorade, Delta Air Lines, Audemars Piguet, Aston Martin, Pepsi, Beats by Dre headphones, Mission Athletecare, Berlei bras, OPI Products, OnePiece, IBM, Mini and Chase Bank.

Fashion

Williams was once known for her unusual and colorful outfits on court. In 2002, there was much talk when she wore a black lycra catsuit at the US Open. At the 2004 US Open, Williams wore denim skirts and knee-high boots—tournament officials, however, did not allow her to wear the boots during matches. At Wimbledon in 2008, the white trench coat she wore during warm-up for her opening match was the subject of much discussion since it was worn despite the sunny weather. Off-court, Williams has also presented new designs. In November 2004, at the London premiere of After the Sunset she wore a red gown that had a near-topless effect.

Williams formerly had a special line with Puma. In April 2004, she signed a deal worth US$40 million for a line with Nike. Since 2004, she has also been running her own line of designer apparel called "Aneres"—her first name spelled backward. In 2009 she launched a signature collection of handbags and jewelry. The collection, called Signature Statement, is sold mainly on the Home Shopping Network (HSN).

In early 2010, Williams became a certified nail technician in preparation for her upcoming nail collection with a company called HairTech.

In 2015, she became the first black female athlete to have a picture by herself on the cover of Vogue, which she did for the April 2015 issue.

In 2015 she also presented her HSN Signature Statement collection for the second time at the New York Fashion Week Show‍—‌a clothing line exclusively made for the retailer HSN.

Entertainment

Williams has appeared on television and also provided voice work on animated shows: in a 2001 episode of The Simpsons Serena joined the animation along with sister Venus, Pete Sampras and Andre Agassi. She has also provided guest voice work in a 2005 episode of Playhouse Disney's animated kids show Higglytown Heroes and a 2007 episode of the Nickelodeon cartoon Avatar: The Last Airbender, which she has described as her "favorite show".

Williams has posed for the 2003 and 2004 editions of the Sports Illustrated Swimsuit Issue. In April 2005, MTV announced plans to broadcast a reality show around the lives of Serena and Venus, which was eventually aired on ABC Family. Williams has appeared twice on MTV's Punk'd and in 2007, appeared in the ABC reality television series Fast Cars and Superstars: The Gillette Young Guns Celebrity Race. In 2002, she played Miss Wiggins in the season 3 episode "Crouching Mother, Hidden Father" of My Wife and Kids; she has also guest-starred during episodes of The Bernie Mac Show, ER and Law & Order: Special Victims Unit. In 2007 Williams appeared in the music video of "I Want You" by the American rapper Common, alongside performers Alicia Keys and Kanye West.

In late 2009, Williams became the first active female professional athlete to appear in a feminine hygiene product advertising campaign. A series of online videos and print advertisements for Tampax Pearl tampons showed her hitting balls at Mother Nature, played by Catherine Lloyd Burns, to prevent Mother Nature giving her a red-wrapped gift, representing her menstrual period. In the online videos, the two have dueling press conferences over the "bad blood" between them. "A lot of celebrities are not open to working with our brand, and we're thrilled that Serena is", said a brand manager for Tampax at Procter & Gamble.

In July 2012, she appeared in the ABC comedic improv television series Trust Us With Your Life and as a lawyer on the Lifetime television series Drop Dead Diva.

To celebrate the 35th anniversary of Pac-Man, Williams made a cameo appearance in the movie Pixels, which starred Adam Sandler and Kevin James, and premiered on July 24, 2015.

Language fluency

In addition to English as her native language Williams also speaks conversational French, and knows some Spanish and Italian. At the 2013 and 2015 French Open she gave her on-court interviews in French, much to the crowd's delight.

Miami Dolphins venture

In August 2009, Williams and her sister Venus became minority owners of the Miami Dolphins after purchasing a small stake in the team. Their home in Palm Beach Gardens, Florida, is about an hour's drive from the Dolphins' stadium. They are the first African-American women to hold any amount of ownership in an NFL franchise. Stephen Ross, the majority owner of the Dolphins, said "We are thrilled to have Venus and Serena join the Dolphins as limited partners. They are among the most admired athletes in the world and have become global ambassadors for the game of tennis."

Charity work

In 2008, as part of the Serena Williams Foundation's work, Williams helped to fund the construction of the Serena Williams Secondary School in Matooni, Kenya. The Serena Williams Foundation also provides university scholarships for underprivileged students in the United States. She received a Celebrity Role Model Award from Avon Foundation in 2003 for work in breast cancer. Williams has also been involved in a number of clinics at schools and community centers, particularly those which have programs focusing on at-risk youth. She has also won the "Young Heroes Award" from Big Brothers Big Sisters of Greater L.A. and Inland (2003) and the "Family Circle and Prudential Financial Player Who Makes a Difference Award" (2004). In response to the 2010 Haiti earthquake, Williams, along with other ATP and WTA stars decided to forgo their final day of preparation for the 2010 Australian Open to form a charity event in which all proceeds will go to the Haiti earthquake victims. Serena, along with her sister Venus, is a supporter and contributor of First Serve Miami, a foundation for youth who want to learn tennis but are socially and economically challenged. She has been an International Goodwill Ambassador with UNICEF since 2011 and has helped launch UNICEF's Schools for Asia campaign.

Williams' return to Indian Wells in 2015 was done in partnership with the Equal Justice Initiative, a non-profit organization that provides legal representation to those who may have been denied a fair trial. EJI executive director Bryan Stevenson lauded her courage in supporting his organization. "It's so rare when athletes at the top of their game are willing to embrace a set of issues that, for a lot of people, are edgier", he said. "This is not aid to orphans ... She was standing when a lot of her contemporaries remain seated, speaking up when others are being quiet."

Other charitable organizations Williams supports include the Elton John AIDS Foundation, Great Ormond Street Hospital, Hearts of Gold, the Common Ground Foundation, the Small Steps Project, the HollyRod Foundation, Beyond the Boroughs National Scholarship Fund, World Education, the Eva Longoria Foundation, the Caliber Foundation and the Cure for MND Foundation.

Writing

The Williams sisters, with author Hilary Beard, wrote a book titled Venus & Serena: Serving From The Hip: 10 Rules For Living, Loving and Winning, which was published in 2005. During the 2009 Wimbledon Championships, Williams said that she is in the process of writing a TV show storyline, which will be converted into script form by her agency. She stated that the show will represent subject matter from a mix of popular American television shows such as Desperate Housewives, and Family Guy. Williams released her first solo autobiography entitled On the Line, following the 2009 US Open.

Personal life

On September 14, 2003 Williams' elder half-sister Yetunde Price was shot to death. Yetunde sometimes worked as a personal assistant to both Venus and Serena Williams. Her killer was convicted of voluntary manslaughter, and was sentenced to 15 years in prison.

Serena dated actor Jackie Long from 2007 to 2008. She was also in a relationship with rapper/actor Common from 2008 to 2010.
