Valve took the opportunity of GDC today to announce its latest enhancement for Steam: "big picture" mode. What's "big picture" mode, you ask?

"With big picture mode, gaming opportunities for Steam partners and customers become possible via PCs and Macs on any TV or computer display in the house," Valve marketing veep Doug Lombardi said in a press release. Valve will be sharing details of "big picture" mode with devs and pubs at GDC, showing off "controller support and navigation designed for television interaction." It sounds like you home theater PC owners may be in for a treat.
