After sitting on the sidelines as the new multiscreen ecosystem evolved for the pay TV industry, Discovery Communications has joined the TV Everywhere movement with the launch of Discovery Go, an app featuring aggregated access to live TV feeds and on-demand shows from nine U.S. networks from the programmer’s stable ?? Discovery Channel, TLC, Animal Planet, Investigation Discovery, Science Channel, Velocity, Destination America, American Heroes Channel and Discovery Life.

The programmer is launching Discovery Go in connection with the December 2 global premiere of Discovery Channel’s Racing Extinction , a doc “chronicling the plight of the world’s most endangered species.”

Discovery Go will let users locate programs organized into fourteen genres, including Survival and History, and access curated playlists. Users also can also use the app to build their own watch-lists.

Discovery said the app will feature “top series” on an on-demand basis and the day after they debut on the linear networks, including Gold Rush, 90 Day Fiance, 7 Little Johnstons, Pit Bulls and Parolees, Survivorman and Homicide Hunter .

Early on, Discovery Go, which requires credentials from MVPDs with TVE rights for the full experience, is being offered on the Web (at DiscoveryGO.com ) and via apps for iOS and Android smartphones and tablets, with more platform launches promised in the “coming months.”

“The launch of?Discovery GO?represents an important first step in providing viewers with access to our award-winning content anytime, anywhere on practically any device,” said Paul Guyardo, chief commercial officer, Discovery Communications, in a statement. “This aggregated TVE streaming service and strong user experience is made possible by Discovery’s 30-year commitment to content ownership and our global learnings in the space, and also serves as an important promotional platform to complement and support our TV brands. We look forward to giving pay-TV customers more of what they want in?Discovery GO.”

“Compelling authenticated offerings are essential to our relationships with viewers and distributors, and we are proud to join with our MVPD partners to bring?Discovery GO?to audiences ? providing a robust lineup of programming and even greater value to subscribers across the U.S.,” added Bruce Campbell, Discovery’s chief development, distribution & legal officer.?
