and Valve announced that Steam had become profitable because of some highly successful Valve games.Although digital distribution could not yet match retail volume, profit margins for Valve and developers were far larger on Steam.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).Initially, Valve was required to be the publisher for these titles since they had sole access to the Steam's database and engine, but with the introduction of the Steamworks software development kit (SDK) in May 2008, anyone could potentially become a publisher to Steam, outside of Valve's involvement to curate titles on the service.
Prior to 2009, most games released on Steam had traditional anti-piracy measures, including the assignment and distribution of product keys and support for digital rights management software tools such as Secu ROM or non-malicious rootkits.
Mobile apps with connected functionality with the main software were later released for i OS, Android, and Windows Phone devices in the 2010s.
