Major League Gaming

Major League Gaming Corp. (MLG) was a professional esports organization based in New York City. Founded in 2002 by Sundance DiGiovanni and Mike Sepso, MLG held official video game tournaments throughout the United States and Canada. The Boost Mobile MLG Pro Circuit was a television broadcast of Halo 2 MLG tournaments in 2006 and 2007, ESPN.com, and other broadband sites. The company was also involved in television production, and game development. MLG's aim was to elevate computer and console game tournaments to viable competitive and spectator events.

In January 2016, video game publisher Activision Blizzard announced its acquisition of Major League Gaming. The company, whose own esports division was led by MLG co-founder Mike Sepso, stated that it intended to leverage the purchase as part of its plans to build an esports-focused television network.

The organization experienced a loss of profit, leading its parent company, Activision Blizzard, to close its last branch in January 2024.

The MLG Pro Circuit roster included Starcraft II and League of Legends for the PC. Mortal Kombat, Soul Calibur V, and King of Fighters XIII for the PlayStation 3, and Super Smash Bros. Melee for GameCube were the only console games. Fighting games were commented by Juicebox Abel, Tom Brady (not to be confused with the NFL quarterback), and Bibulus. No League of Legends casters have been announced.

Major League Gaming hosted a series of online qualifier ladders for the online-only pro circuit titles leading to the national championship. In the past, MLG hosted Super Smash Bros. Melee tournaments during the 2004 through 2006 MLG Circuit and other games such as Halo: Combat Evolved, Halo 2, Tekken 5, Gears of War, Tom Clancy's Rainbow Six: Vegas, Shadowrun, Tom Clancy's Rainbow Six: Vegas 2, Call of Duty 4, and Gears of War 2.

Each team/player was required to purchase a team pass to compete. These passes normally went on sale several weeks in advance of the next Pro Circuit event. Passes were limited, so participants were encouraged to purchase a pass as soon as they went on sale.

The MLG Pro League was a Call of Duty league that ran in 2014 and 2015 for Ghosts and Advanced Warfare respectively. There were three seasons per year, and 16 teams competing per season. The regular season was played online in a round-robin tournament format over the course of two months. At the end of each season, the bottom four teams were sent to a relegation tournament and the top eight teams were invited to an offline playoff tournament.

There was also a Dota 2 Pro League sponsored by joinDota.
