Dish Network said its Sling TV online TV service will offer HBO in time for the premium cabler’s “Game of Thrones” and “Silicon Valley” season premieres April 12, under a broader pact between the satcaster and Time Warner Inc.

HBO will be available on the over-the-top service for $15 per month, in addition to Sling TV’s $20 monthly baseline price. That will include one live channel and the same on-demand library that HBO provides on its other platforms, including HBO Go, with access to every original series from the network.

HBO also is launching HBO Now — which doesn’t require subscribing to any cable, satellite or telco TV service — with Apple TV and Cablevision Systems as a standalone service.

“Sling TV is bringing HBO to our customers on all of our supported devices in time for one of the most important TV moments of the year,” Roger Lynch, CEO of Dish’s Sling TV, said in announcing the launch. “HBO delivers hit shows and movies that TV viewers crave, and with this addition we’re adding another heavy hitter to a lineup that includes ESPN, AMC, TNT and more.”

The Sling TV pact for HBO was part of a larger, multiyear agreement between Dish and Time Warner’s Turner Broadcasting and HBO, announced Wednesday. That ensures continued carriage on Dish of TNT, TBS and other Turner nets on Dish, which last fall dropped CNN, Cartoon Network and five of the programmer’s smaller nets for about a month before the parties reached a temporary resolution.

Sling TV, officially launched in February, currently provides 20 networks in its core $20-per-month lineup — a slimmed-down bundle aimed as price-sensitive, younger consumers who are averse to full-blown pay-TV. The key property here is ESPN: It’s the priciest cable net in the biz at around $6 per month per sub on a wholesale basis. Others include AMC, TNT, TBS, Food Network, HGTV, Travel Channel, Disney Channel, CNN, A&E, History and Lifetime. Sling TV also offers optional $5-per-month add-on tiers.

In a statement, Tom Woodbury, president of global distribution for HBO, added: “It has always been our desire to make the HBO subscription widely accessible. Sling TV is a part of that ongoing evolution, and we believe HBO is a great addition to the platform.”
