Valve announced today that Steam will expand its offerings to include non-gaming software
The first patch of non-gaming software will be available for purchase through Steam on September 5th, 2012. Valve didn’t reveal any specific software titles, but it announced that its offerings will "range from creativity to productivity" and that they "will take advantage of popular Steamworks features, such as easy installation, automatic updating, and the ability to save your work to your personal Steam Cloud space so your files may travel with you."
More Software titles will be added in an ongoing fashion following the September 5th launch, and developers will be able to submit Software titles via Steam Greenlight.
"The 40 million gamers frequenting Steam are interested in more than playing games," said Mark Richardson at Valve. "They have told us they would like to have more of their software on Steam, so this expansion is in response to those customer requests."
