Major League Gaming

''This article is about the professional gaming company. For the Halo 3 playlist, click here.''

Overview
Major League Gaming (MLG) is the largest organized league for worldwide professional competitive gaming and tournaments. The privately held company was founded in New York City in 2002, and has now attracted competitors from over 28 countries worldwide. MLG uses several media outlets to popularize their tournaments, mainly through TV, via ESPN in the USA. However, the internet is much more useful to fans, as MLG posts videos, tactics, leaderboards, tips from professional gamers, and much more. Fans can visit MLG's website to upload their videos to the site, and to access the content of their favorite game that MLG currently uses, some of which are: Gears of War 2, Rainbow Six: Vegas 2, Call of Duty 4, and Halo 3.

MLG also runs a video series in partnership with ESPN called MLG/ESPN Top Ten, in which ten short clips of unusual or exceptional Halo 3 multiplayer matches of the week are presented in a quick, concise manner. Fans can submit their videos for consideration to be included in the MLG/ESPN Top Ten at mlgpro.com

Tournaments
MLG's main function is to organize tournaments and competitions and present leaderboards of the top competitors of a game. MLG's most famous tournament series is the MLG Pro Circut. This is an annual series of tournaments held by MLG in which competitors of all games compete at various locations, usually a major city, in the United States (One event has been held in Toronto, Canada. The current Pro Circut is the MLG Pro Circut 2008 which runs from April 11 to November 3, and has 6 tournaments including the championship. Because MLG is fully sponsored, players competing in an MLG tournament are provided with all necessary equipment such as televisions and video game systems, except game controllers. However, some players may choose to bring equipment anyway to practice their game before the competition. Typically, each MLG tournament is held over the course of a weekend (Friday through Sunday) with the only exception being the Playoffs/Championship, which occurs over a period of four days. MLG has tweaked the gametypes and, in the case of Halo 3, the maps to provide highly competitive gameplay for a wide variety of basic gametypes such as: Capture the Flag, Team Slayer, and Team King of the Hill. The MLG gametypes tend to be much more fast paced than default settings. The current official MLG gametypes and settings (version 5) can be found here.

Pro Circuit Ladders
Players wishing to participate in an MLG tournament compete in online tournaments called Pro Circuit Ladders which, by winning, players may earn Pro Circuit Rank Points. These Pro Circuit Rank Points determine seeding for the Pro Circuit events, and often offer cash prizes. The Pro Circuit Ladder is split into two groups, the Ladder Competition, and the Playoff Bracket. Top teams in the Ladder Competition, who compete over several weeks of tournaments, earn a spot in the Playoff Bracket. The Playoff Bracket is a double-elimination tournament to determine an overall victor. To enter Pro Circut Ladders, players require MLG/Gamebattles Credits which can be purchased in the MLG online store.
