The Proleague was the Premier Brood War Team League, It was formerly hosted on both cable channels, OnGameNet and MBCGame, while a company called IEG held the broadcasting rights. It is now solely broadcast on OGN as MBC closed down its gaming doors.
In 2012, ProLeague switched from Brood War to StarCraft II, first holding a Hybrid League, then fully switching later in the year.

 Map Pool
The maps get renewed every season. These are often commissioned by KeSPA for the Proleague. The 2008-09 season of Proleague was the first to feature periodic breaks, during which KeSPA could change the map pool. They took advantage of that rule for the first time in November 2008 switching the map Raid Assault II for Rush Hour 3. The Map Pool for a specific season can be found on a seasons overview page.
The Proleague has been through many Format changes since its creation in 2003, The current season uses a Best of 5 match up, for the Regular season, the finals will be a Best of 7, in either instance, no player may play twice per match.
