Steam is a digital distribution, digital rights management, multi-player and communications platform developed by Valve Corporation, and has been widely used to distribute a wide range of games and related media entirely over the internet. The network gained more widespread use after the release of Half-Life 2 in 2004, which was intrinsically integrated into the system. Steam has since expanded as other major publishers, including Eidos Interactive, Activision, Ubisoft and Electronic Arts began distributing a number of their titles over the system.
