The English Football League Championship, known simply as the Championship in England and for sponsorship purposes as Sky Bet Championship, is the highest division of the English Football League (EFL) and second-highest overall in the English football league system after the Premier League, and is currently contested by 24 clubs. Introduced for the 2004–05 season as the Football League Championship, the division is a rebrand of the former Football League First Division, which itself is a rebrand of the now-defunct Football League Second Division prior to the 1992 launch of the Premier League. The winning club of this division each season receives the EFL Championship trophy, which was the previous trophy awarded to the winners of the English top-flight prior to the launch of the Premier League. As with other divisions of professional English football, Welsh clubs can be part of this division, thus making it a cross-border league. Each season, the two top-finishing teams in the Championship are automatically promoted to the Premier League. The teams that finish the season in 3rd to 6th place enter a playoff tournament, with the winner also gaining promotion to the Premier League. The three lowest-finishing teams in the Championship are relegated to League One. The Championship is the wealthiest non-top-flight football division in the world, the ninth-richest division in Europe, and the tenth best-attended division in world football (with the highest per-match attendance of any secondary league). Its average match attendance for the 2018–19 season was 20,181. Barnsley have spent more seasons in this division than any other team, with Birmingham City currently holding the longest tenure in this division, only absent in the 2010–11 season. Barnsley became the first club to attain 1,000 wins in second-tier English league football with a 2–1 home victory over Coventry City on 3 January 2011 and also the first club to play 3,000 games in second-level English league football (W1028, D747, L1224). History Sunderland won the league in the first season since re-branding, with Wigan Athletic finishing second to win promotion to the top flight of English football for the first time in their history. They had only been elected to the Football League in 1987; playing in the fourth tier as recently as 1994 before their promotion. West Ham United won the first Championship play-off final that season, following a 1–0 victory over Preston North End at the Millennium Stadium in Cardiff. The 2004–05
