The Premier League (officially known as the Barclays Premier League for sponsorship reasons), is a professional league competition for football clubs located at the top echelon of the English football league system.
It is the world's most watched sporting league and also the most lucrative. Based on the performances of member clubs in European competitions over a five-year period, with the 2006/07 season results in consideration, the Premier League is unofficially ranked second behind Spain's 'La Liga, but ahead of Italy's 'Serie A' in the UEFA rankings of European leagues. This is an improvement on the third place from the official rankings up to the 2005–06 season.
The FA Premier League (as it was then known) was formed in 1992 from the clubs in the top division of The Football League, and is currently contested by twenty clubs. In a total of fifteen seasons, the title has been won by only four teams:
Manchester United (nine times),
Arsenal (three times),
Chelsea (twice), and
Blackburn Rovers (once).
The current Premier League champions are Manchester United, who won the title with two games remaining of the 2006–07 season.
