[9] MLG's aim was to elevate computer and console game tournaments to viable competitive and spectator events.

The company, whose own esports division is 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.

Mortal Kombat, Soul Calibur V, and King of Fighters XIII for the PlayStation 3, and Super Smash Bros. Melee for GameCube are the only console games.

Major League Gaming also hosts 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.

Call of Duty: Modern Warfare 2 made its debut on the Online Pro Circuit on MLG's GameBattles website for PlayStation 3.

[20] The 2011 Circuit featured four titles: Halo: Reach, Starcraft 2, Call of Duty: Black Ops and the mid-season addition of League of Legends.

The team with the best record throughout pool play advanced to the winner's bracket semi-finals, securing themselves a Top 6 finish.

The Arenas are Pay-per-view (PPV) events and for now only feature Starcraft II, and are broadcast in high definition (HD) from MLG's Studio in New York.

The deal took effect in June, when KeSPA Brood War pros participated in an exhibition event at MLG Anaheim.

[24] Beginning on November 2, 2012, with the commencement of the MLG Fall Championship in Dallas, Texas, Halo was reintroduced to the pro circuit.

Activision Blizzard operates its own in-house esports division, Activision Blizzard Media Networks, led by veteran sports television executive Steve Bornstein, MLG co-founder Mike Sepso, and its acquisition of assets from the defunct IGN Pro League.

Despite the acquisition, MLG will continue to host events relating to games that are not published by Activision Blizzard's subsidiaries.

[33] In May 2016, MLG announced "Enhanced Viewing Experience", a new streaming player design that integrates live data and statistic displays.

Several professional Call of Duty players including Matt "Nadeshot" Haag have signed exclusivity contracts with the streaming service.
