Sling TV adding live and on-demand HBO in new $15 add-on tier

Unlike HBO Now — which is exclusive to Apple at launch — consumers will not be able to purchase HBO access from Sling TV independently. Instead, they will need to subscribe to Sling's $20-per-month base plan, then add the new HBO package, bumping the total cost to $35 per month.

Additionally, HBO on Sling TV will include just one of HBO's 13 channels, though subscribers will gain access to the entire on-demand catalog.

"It is has always been our desire to make the HBO subscription widely accessible," HBO distribution executive Tom Woodbury said in a release. "Sling TV is a part of that ongoing evolution and we believe HBO is a great addition to the platform."

There is no word on exactly when HBO will launch on Sling TV, but it will bow within the next two weeks, in time for the season premier of Game of Thrones. The same is true for HBO Now, which Apple announced during its "Spring Forward" event in March.
