Canadian publisher Strategy First announced in December 2005 that it would partner with Valve for digital distribution of current and future titles.
Mobile apps with connected functionality with the main software were later released for i OS, Android, and Windows Phone devices in the 2010s.
The Steam platform is the largest digital distribution platform for PC gaming, estimated in 2013 to have 75% of the market space.
Since 2007, Valve has continued to expand Steam's functionality and services for consumers and developers.
Steam's primary service is to allow its users to download games and other software that they have in their virtual software libraries to their local computers as game cache files (GCFs).
