The Premier League is an English professional league for association football clubs. At the top of the English football league system, it is the country's primary football competition. Contested by 20 clubs, it operates on a system of promotion and relegation with The Football League.
The competition formed as the FA Premier League on 20 February 1992 following the decision of clubs in the Football League First Division to break away from The Football League, which was originally founded in 1888, and take advantage of a lucrative television rights deal. The Premier League has since become the world's most watched association football league.
Of the 44 clubs to have competed since the inception of the Premier League in 1992, four have won the title: Manchester United (12 titles) Arsenal (3), Chelsea (3) and Blackburn Rovers (1). The current champions are Manchester United, who won the title in the 2010–11 season.
