Valve is to begin selling non-gaming software on Steam later this year.
The Counter-Strike and Half-Life maker said that many of the "creativity" and "productivity" software titles offered on the digital distribution platform 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.
Software titles will launch on Steam on September 5, and developers will be able to submit them via Steam Greenlight.
"The 40 million gamers frequenting Steam are interested in more than playing games," said Valve's Mark Richardson. "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."
Steam offers over 1,800 games, and saw unit sales rise by more than 100 percent for the seventh straight year in 2011.
Valve said last month that Steam's Big Picture mode - the announced but still under wraps new feature that'll bring Steam games to your TV - is "coming soon".
