Valve announces a major update to the Steam gaming platform called Big Picture. Steam's new Big Picture mode lets gamers access all of their favorite Steam games on a television. With the press of a button, Steam displays a new full-screen user interface optimized for readability and interaction on TV. Big Picture has been designed to be used with a traditional game controller, while also fully supporting keyboard and mouse input.

Steam gamers can experience Big Picture by connecting their PC or Mac to a TV, typically with a single HDMI cable. Access to the complete Steam store is included, as is the Steam Community. In addition to their complete library of Steam games, each user's cloud files, Steam Workshop content, account information and preferences will be accessible automatically in the new mode.

"Sega's roots are in living-room gaming." said John Clark, Vice President of Digital Distribution at Sega. "For the first time since the advent of PC games decades ago, gamers are finally going to have access to the kind of entertainment experience we've always wished they could have with our PC titles - one that's incredibly social, comfortable, and accessible. We're excited about the opportunity, and Big Picture has inspired us to bring even more of our titles to Steam in the future."

"There is nothing more satisfying than slaying thousands of orcs on your big screen. And many of the most die-hard players of Orcs Must Die 2 have always preferred playing with a game controller. Steam's Big Picture mode finally marries these two and delivers a true living room entertainment experience to players."

"We're pleased that gamers on Steam will now be able to immerse themselves in our entertainment experiences in the comfort of their living room on large sc reen TVs," said Steve Glickstein of Take-Two Interactive Software. "From action and adventure to sports and sims, our titles deliver big fun on big screens."

"PC gaming continues to be the leading edge of entertainment, whether it's social gaming, MMOs, graphics hardware, free-to-play, or competitive gaming," said Gabe Newell, president of Valve. "With Big Picture for Steam, we are trying to do our part to give customers and developers what they want - their games, everywhere, optimized for the environment in which they are playing."

Big Picture also includes a new web browser designed for televisions and game controllers. It is accessible from anywhere within the Big Picture UI, and even while playing Steam games on a TV. It supports Big Picture's new method of typing with a game controller, which is useful for entering URLs, filling out forms, chatting, and other functions.
