Entertainment Software Association
The Entertainment Software Association (ESA) is the trade association of the video game industry in the United States. It was formed in April 1994 as the Interactive Digital Software Association (IDSA) and renamed on July 16, 2003. It is based in Washington, D.C..
Most of the top publishers in the gaming world (or their American subsidiaries) are members of ESA, including Capcom, Disney Interactive Studios, Electronic Arts, Konami, Microsoft, Namco Bandai Games, Nintendo, Sega, Sony Computer Entertainment, Square Enix, Take-Two Interactive, Ubisoft and Warner Bros. Interactive Entertainment.
The ESA’s policy is based by member companies serving on the ESA’s three Working Groups:
- Intellectual Property Working Group
- Public Policy Committee
- Public Relations Working Group
Doug Lowenstein founded the ESA. On December 14, 2006, game blog Kotaku reported that he was resigning to take a job in finance outside the industry. On May 17, 2007, Mike Gallagher replaced Doug Lowenstein as the president of ESA.
On August 18, 2007, it was discovered that someone from an IP address belonging to the ESA modified the modchip and abandonware articles in Wikipedia, by changing article content to represent legal opinions held by the ESA.
Controversial Support for SOPA and PIPA
In 2012, frustrated by the Entertainment Software Association‘s support of the proposed anti-piracy SOPA and PIPA legislation, Red 5 Studios CEO Mark Kern founded the League For Gamers (LFG), which intends to advocate for gamers' interests, which may conflict with the industry protection measures the ESA advocates. 
To effectively combat this, users of the Bit Torrent client are able to thwart the ESA by using a number of IP hiding methods, including VPN, PeerBlock and Proxy servers.  Websites however have a much more difficult time and have to resort from moving around or getting hosted in countries that do not honor WIPO.
The ESA has also been known to lobby congress in order to get laws passed that benefit the industry's copyright protection. According to a Bloomberg report, The Entertainment Software Association spent approximately $1.1 million in the first quarter of 2011 on lobbying efforts in Washington D.C. 
Gregory Boyd, chairman of the Interactive Entertainment Group at the New York law firm stated that “when it comes to lobbying, the "main industry group" that individual companies defer to is the Entertainment Software Association (ESA), which spent $4.83 million on its own in 2012 — more than Facebook, Google, or even the National Rifle Association (NRA).
