Customers that have Sling TV will notice that the service has added HBO to its programming lineup. The new add-on can be yours for $15 per month, making it the only live Internet TV service to offer HBO’s content on both a linear and Video-On-Demand basis.

In time for the “Game of Thrones” and “Silicon Valley” season premieres on April 12, HBO is now available to subscribers of Sling TV’s “Best of Live TV” core package or select Sling International programming packages. Customers can watch HBO on all Sling TV-supported devices including: Amazon Fire TV and Fire TV Stick, current-generation Roku players and Roku TV models, Xbox One, Android and iOS devices, and Macs and PCs.

“We continue to give TV lovers the content they want on the devices they already own,” said Roger Lynch, CEO of Sling TV. “We know Sling TV is the only way most of our customers can watch HBO shows like ‘Game of Thrones’ live. Adding HBO’s live and extensive on-demand content to our lineup highlights our continued commitment to bringing customers the very best programming.”

The new offering features HBO’s main live channel and will include the same VOD library HBO provides on its other platforms; Sling TV will begin adding HBO’s VOD titles today. Sling TV will also provide its customers with access to three streams of HBO, in addition to the single-stream dedicated to its core and add-on packages. Multi-stream functionality for HBO will be added to customer accounts on a rolling basis starting today.
