The terminology can also be used to describe forms of competition of two-wheeled motorised vehicles under the banner of motorcycle racing, and includes off-road racing such as motocross.

Four- (or more) wheeled motorsport competition is globally governed by the Fédération Internationale de l'Automobile (FIA); and the Fédération Internationale de Motocyclisme (FIM) governs two-wheeled competition. Likewise, the Union Internationale Motonautique (UIM) governs powerboat racing while the Fédération Aéronautique Internationale (FAI) governs air sports; including aeroplane racing.

Grand Prix motorcycle racing is the premier class of motorcycle road racing events held on road circuits sanctioned by the Fédération Internationale de Motocyclisme (FIM). Independent motorcycle racing events have been held since the start of the twentieth century[1] and large national events were often given the title Grand Prix.[2] The foundation of the Fédération Internationale de Motocyclisme as the international governing body for motorcycle sport in 1949 provided the opportunity to coordinate rules and regulations in order that selected events could count towards official World Championships. It is the oldest established motorsport world championship.[3]

Grand Prix motorcycles are purpose-built racing machines that are unavailable for purchase by the general public and unable to be ridden legally on public roads. This contrasts with the various production-based categories of racing, such as the Superbike World Championship and the Isle of Man TT Races that feature modified versions of road-going motorcycles available to the public. The current top division is known as MotoGP since 2002 when the four-stroke era began. Prior to that, the largest class was 500cc, both of which form a historical continuum as the official World Championship, although all classes have official status.

The championship is currently divided into four classes: the eponymous MotoGP, Moto2, Moto3 and MotoE. The first three classes use four-stroke engines, while the MotoE class (new in 2019) uses electric motorcycles. The 2019 MotoGP season comprises 19 Grands Prix, with 12 held in Europe, three in Asia, two in the Americas, and one each in Australia andù the Middle East.

The most successful rider in Grand Prix history is Giacomo Agostini with 15 titles and 122 race wins. In the top-flight series, Agostini holds the title record with eight, followed by active riders Valentino Rossi with seven and Marc Márquez with six. As of 2019, Rossi holds the record for most top-flight race wins with 89.

Amateur boxing is both an Olympic and Commonwealth Games sport and is a standard fixture in most international games—it also has its own World Championships. Boxing is overseen by a referee over a series of one-to-three-minute intervals called rounds.

A winner can be resolved before the completion of the rounds when a referee deems an opponent incapable of continuing, disqualification of an opponent, or resignation of an opponent. When the fight reaches the end of its final round with both opponents still standing, the judges' scorecards determine the victor. In the event that both fighters gain equal scores from the judges, professional bouts are considered a draw. In Olympic boxing, because a winner must be declared, judges award the contest to one fighter on technical criteria.

While humans have fought in hand-to-hand combat since the dawn of human history, the earliest evidence of fist-fighting sporting contests date back to the ancient Near East in the 3rd and 2nd millennia BC.[2] The earliest evidence of boxing rules date back to Ancient Greece, where boxing was established as an Olympic game in 688 BC.[2] Boxing evolved from 16th- and 18th-century prizefights, largely in Great Britain, to the forerunner of modern boxing in the mid-19th century with the 1867 introduction of the Marquess of Queensberry Rules.

Football is played in accordance with a set of rules known as the Laws of the Game. The ball is 68–70 cm (27–28 in) in circumference and known as the football. The two teams each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to represent their team in the coin toss prior to kick-off or penalty kicks.[4]

Players are not allowed to touch the ball with hands or arms while it is in play, except for the goalkeepers within the penalty area. Other players mainly use their feet to strike or pass the ball, but may also use any other part of their body except the hands and the arms. The team that scores most goals by the end of the match wins. If the score is level at the end of the game, either a draw is declared or the game goes into extra time or a penalty shootout depending on the format of the competition.

It is distinguished by not running on a circuit, but instead in a point-to-point format in which participants and their co-drivers drive between set control points (special stages), leaving at regular intervals from one or more start points. Rallies may be won by pure speed within the stages or alternatively by driving to a predetermined ideal journey time within the stages.

Manchester United have won more trophies than any other club in English football,[5][6] with a record 20 League titles, 12 FA Cups, five League Cups and a record 21 FA Community Shields. United have also won three UEFA Champions Leagues, one UEFA Europa League, one UEFA Cup Winners' Cup, one UEFA Super Cup, one Intercontinental Cup and one FIFA Club World Cup. In 1998–99, the club became the first in the history of English football to achieve the continental European treble.[7] By winning the UEFA Europa League in 2016–17, they became one of five clubs to have won all three main UEFA club competitions.

The 1958 Munich air disaster claimed the lives of eight players. In 1968, under the management of Matt Busby, Manchester United became the first English football club to win the European Cup. Alex Ferguson won 38 trophies as manager, including 13 Premier League titles, 5 FA Cups and 2 UEFA Champions Leagues, between 1986 and 2013,[8][9][10] when he announced his retirement. Manchester United is one of the most widely supported football clubs in the world,[11][12] and has rivalries with Liverpool, Manchester City, Arsenal and Leeds United.

Manchester United was the highest-earning football club in the world for 2016–17, with an annual revenue of €676.3 million,[13] and the world's third most valuable football club in 2019, valued at £3.15 billion ($3.81 billion).[14] After being floated on the London Stock Exchange in 1991, the club was taken private after a purchase by Malcolm Glazer in 2005 at almost £800 million, of which over £500 million of borrowed money became the club's debt.[15] From 2012, some shares of the club were listed on the New York Stock Exchange, although the Glazer family retains overall ownership and control of the club.

Professional athleticism has come to the fore through a combination of developments. Mass media and increased leisure have brought larger audiences, so that sports organizations or teams can command large incomes.[1] As a result, more sportspeople can afford to make athleticism their primary career, devoting the training time necessary to increase skills, physical condition, and experience to modern levels of achievement.[1] This proficiency has also helped boost the popularity of sports.[1] Most sports played professionally also have amateur players far outnumbering the professionals.

Arsenal was the first club from the South of England to join The Football League, in 1893, and they reached the First Division in 1904. Relegated only once, in 1913, they continue the longest streak in the top division,[3] and have won the second-most top-flight matches in English football history.[4] In the 1930s, Arsenal won five League Championships and two FA Cups, and another FA Cup and two Championships after the war. In 1970–71, they won their first League and FA Cup Double. Between 1989 and 2005, they won five League titles and five FA Cups, including two more Doubles. They completed the 20th century with the highest average league position.[5]

Herbert Chapman, who changed the fortunes of Arsenal forever, won the club its first silverware, and his legacy led the club to dominate the 1930s decade; Chapman, however, died of pneumonia in 1934, aged 55. He helped introduce the WM formation, floodlights, and shirt numbers;[6] he also added the white sleeves and brighter red to the club's jersey.[7] Arsène Wenger was the longest-serving manager and won the most trophies. He won a record seven FA Cups, and his title-winning team set an English record for the longest top-flight unbeaten league run at 49 games between 2003 and 2004,[8] receiving the nickname The Invincibles.

In 1886 munitions workers at the Royal Arsenal in Woolwich founded the club as Dial Square. In 1913, the club crossed the city to Arsenal Stadium in Highbury, becoming close neighbours of Tottenham Hotspur, and creating the North London derby. In 2006, they moved to the nearby Emirates Stadium. In terms of revenue, Arsenal is the ninth highest-earning football club in the world, earned €487.6m in 2016–17 season.[9] Based on social media activity from 2014 to 2015, Arsenal's fanbase is the fifth largest in the world.[9] In 2018, Forbes estimated the club was the third most valuable in England, being worth US$2.24 billion.[10] The motto of the club has long been Victoria Concordia Crescit, Latin for "Victory Through Harmony".

Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.

Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis.[1] It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. During most of the 19th century, in fact, the term tennis referred to real tennis, not lawn tennis.

The rules of modern tennis have changed little since the 1890s. Two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point-challenge system, which allows a player to contest the line call of a point, a system known as Hawk-Eye.

Tennis is played by millions of recreational players and is also a popular worldwide spectator sport. The four Grand Slam tournaments (also referred to as the Majors) are especially popular: the Australian Open played on hard courts, the French Open played on red clay courts, Wimbledon played on grass courts, and the US Open also played on hard courts.

Rugby union is a popular sport around the world, played by male and female players of all ages. In 2014, there were more than 6 million people playing worldwide, of whom 2.36 million were registered players. World Rugby, previously called the International Rugby Football Board (IRFB) and the International Rugby Board (IRB), has been the governing body for rugby union since 1886, and currently has 101 countries as full members and 18 associate members.

In 1845, the first laws were written by pupils at Rugby School; other significant events in the early development of rugby include the decision by Blackheath F.C. to leave the Football Association in 1863 and, in 1895, the split between rugby union and rugby league. Historically rugby union was an amateur sport, but in 1995 formal restrictions on payments to players were removed, making the game openly professional at the highest level for the first time.[3]

The National Hockey League was organized on November 26, 1917, at the Windsor Hotel in Montreal, after the suspension of operations of its predecessor organization, the National Hockey Association (NHA), which had been founded in 1909 in Renfrew, Ontario.[5] The NHL immediately took the NHA's place as one of the leagues that contested for the Stanley Cup in an annual interleague competition before a series of league mergers and foldings left the NHL as the only league left competing for the Stanley Cup in 1926.

At its inception, the NHL had four teams—all in Canada, thus the adjective "National" in the league's name. The league expanded to the United States in 1924, when the Boston Bruins joined, and has since consisted of American and Canadian teams. From 1942 to 1967, the league had only six teams, collectively (if not contemporaneously) nicknamed the "Original Six". The NHL added six new teams to double its size at the 1967 NHL expansion. The league then increased to 18 teams by 1974 and 21 teams in 1979. Between 1991 and 2000, the NHL further expanded to 30 teams. It added its 31st team in 2017 and has approved the addition of a 32nd team in 2021.

Often using a standard deck, poker games vary in deck configuration, the number of cards in play, the number dealt face up or face down, and the number shared by all players, but all have rules which involve one or more rounds of betting.

Chelsea won their first major honour, the League Championship, in 1955. The club won the FA Cup for the first time in 1970 and their first European honour, the UEFA Cup Winners' Cup, in 1971. After a period of decline in the late 1970s and 1980s, the club enjoyed a revival in the 1990s and had more success in cup competitions. The past two decades have been the most successful in Chelsea's history: they won five of its six league titles and the UEFA Champions League during this period.[5] Chelsea are one of five clubs to have won all three of UEFA's main club competitions, and the only London club to have won the Champions League.

The Lakers play their home games at Staples Center, an arena shared with the NBA's Los Angeles Clippers, the Los Angeles Sparks of the Women's National Basketball Association, and the Los Angeles Kings of the National Hockey League.[10] The Lakers are one of the most successful teams in the history of the NBA, and have won 17 NBA championships, tied with the Boston Celtics for the most in NBA history.[11]

The franchise began with the 1947 purchase of a disbanded team, the Detroit Gems of the National Basketball League (NBL). The new team began playing in Minneapolis, Minnesota, calling themselves the Minneapolis Lakers.[12] Initially a member of the NBL, the Lakers won the 1948 NBL championship before joining the rival Basketball Association of America, where they would win five of the next six championships, led by star George Mikan.[13] After struggling financially in the late 1950s following Mikan's retirement, they relocated to Los Angeles before the 1960–61 season.

UEFA represents the national football associations of Europe, runs nation and club competitions including the UEFA European Championship, UEFA Nations League, UEFA Champions League, UEFA Europa League, planned UEFA Europa Conference League, and UEFA Super Cup, and controls the prize money, regulations, and media rights to those competitions.

Henri Delaunay was the first general secretary and Ebbe Schwartz the first president. The current president is Aleksander Čeferin, a former Football Association of Slovenia president, who was elected as UEFA's seventh president at the 12th Extraordinary UEFA Congress in Athens in September 2016, and automatically became a vice-president of the world body FIFA.[3]

MMAFighting.com was launched by Ray Hui in 2001, initially as an Angelfire site.[5]

In 2009, MMAFighting.com was acquired by AOL.[6] In 2011, it was sold to their current owners, Vox Media, where they now are a part of SB Nation.[7]

MMA Fighting features several writers, including senior editor Luke Thomas who is notable on MMAFighting.com as a charter and regular panelist on The MMA Beat web series previously moderated by MMA journalist Ariel Helwani,[8][9] and for his weekly webcast Promotional Malpractice and podcast Monday Morning Analyst.[10] Dave Meltzer, who reports mainly on the business aspect of MMA, as well as Chuck Mindenhall, who writes about the storylines penetrating the MMA community
