The English Football League One (often referred to as League One for short or Sky Bet League One for sponsorship reasons) is the second-highest division of the English Football League and the third tier in the English football league system.
League One was introduced for the 2004–05 season. It was previously known as the Football League Second Division and prior to the advent of the Premier League, the Football League Third Division.
At present (2017–18 season), Oldham Athletic hold the longest tenure in League One, last being out of the division in the 1996–97 season when they were relegated from the First Division. There are currently seven former Premier League clubs competing in the League One, namely Blackpool, Bradford City, Charlton Athletic, Oldham Athletic, Portsmouth, Wigan Athletic, and former Premier League champions Blackburn Rovers.
