England Championship

Sunderland won the league in the first season since rebranding, 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 1978 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 season saw the division announce a total attendance (including postseason) of 9.8 million, the fourth-highest total attendance for a European football division, behind the Premier League (12.88 million), Spain's La Liga (11.57 million) and Germany's Bundesliga (10.92 million). Additionally, Millwall, competing in the inaugural Championship season, qualified for the UEFA Cup, only to lose in the first qualifying round. In the 2005–06 season, Reading broke the Football League points record for a season, finishing with 106 points, exceeding the record of 105 set by Sunderland in 1999.

Sunderland won their second Championship title in the 2006–07 season, after being relegated from the top division the previous season. On 4 May 2007, Leeds United became the first side since the re-branding of the division to enter administration; they were deducted 10 points and were relegated as a result. On 28 May 2007, Derby County won the first Championship play-off final at the new Wembley Stadium, beating West Bromwich Albion 1–0. West Brom would go on to win the Championship in the following season.

On 30 September 2009, Coca-Cola announced they would end their sponsorship deal with the Football League, which began in 2004, at the end of the 2009–10 season.

After winning the 2011 League Cup final, Birmingham City became the first Championship club to compete in the group stage of the UEFA Cup/Europa League, finishing third in the group, only one point behind Portuguese club Braga.

The league had a cumulative attendance of more than 11 million – excluding play-off matches – with more than two million watching Newcastle United and Aston Villa home fixtures alone, both of whom had been relegated from the Premier League in the previous season. This was included in the highest crowds for the second to fourth tier in England since the 1958–59 season. Newcastle won the title in 2016–17, while Aston Villa finished 13th, eventually returning to the Premier League in 2019.

On 13 March 2020, Championship play was halted due to the COVID-19 pandemic, with a suspension lasting until 4 April. It was then extended to the end of April, with the league eventually restarting on 20 June.
