As promised, HBO is now available for Sling TV, Dish network's new Internet TV service. HBO content, which includes live programming like this weekend's Game of Thrones season premiere as well as video-on-demand, is available on PC, as well as devices like Xbox One, Amazon Fire TV, and Roku.

Sling TV starts at $20/month, while an HBO subscription will cost you an extra $15/month.

HBO content was already available on Xbox One through the HBO Go app. But that app requires a cable subscription while Sling TV does not.

Another interesting thing to note is that, while Sling TV normally only allows one stream per account, this isn't true for HBO. Sling will allow users a total of three simultaneous streams.

This new multi-stream functionality will be added "on a rolling basis" beginning today, the company explained.

Sling TV, which requires no contract or extra hardware installation, features channels such as ESPN and ESPN 2, as well as TNT, TBS, Food Network, HGTV, Cartoon Network, and Disney Channel.

By comparison, Sony's $50/month PlayStation Vue streaming TV service does not offer HBO. You can see a detailed Sling TV vs. Vue breakdown here.
