Microsoft has begun to roll out an update for its Xbox Live service that includes new on-demand content from Comcast, along with apps from HBO and MLB, GigaOM reported on Monday. The launch these services will give users the ability to search through a wide range of content directly from their game console. In October, Microsoft announced a number of new content partners that would deliver movies, television shows and other content to its popular Xbox 360 game console. The system had already received updates that included apps from Verizon, Epix, Vevo, Vudu and YouTube. The launch of HBO Go comes as little surprise. In February, the company’s co-president Eric Kessler told reporters that the Xbox HBO Go app would go live on April 1st, in time for the season premiere of “Game of Thrones.” Microsoft fans noted that the company always releases updates on Tuesdays, however, and it was unlikely for HBO to roll out an update the day of the premiere to avoid download complications.
