A new report from the PC Gaming Alliance into the state of the platform in 2008 has revealed that the "largest single platform for games" took around USD 11 billion over the course of the 12 months.
It also noted the growth of digital distribution on the platform, driven by the continuing success of services such as Steam, the growth of free-to-play titles utilising micro-transactions, and the sale of game cards at retail chains.
MMOs were cited as one of the major sources of income for the PC games industry, noting World of Warcraft's USD 1 billion-plus contribution as well as several Asian MMOs taking USD 100 million apiece.
