Microsoft announced on Monday via its blog that it will be selling its Mediaroom properties to Ericsson, in a deal that will see Ericsson become the dominant IPTV player in the industry with over 25 percent market share. Mediaroom operates as a pretty much separate company from Microsoft, with its own HQ in Mountain View and around 400 employees, and powers TV offerings like AT&T U-verse, as well as services from Deutsche Telekom, Telefonica and Telus. The deal clears the deck for Microsoft to go all-in on Xbox as the focal point of its own TV efforts. At Ericsson, Mediaroom will continue to operate essentially as per usual, with that company investing in growing the business, while at Microsoft, the sale allows Microsoft to dedicate “all TV resources to Xbox in a continued mission to make it the premium entertainment service that delivers all the games and entertainment consumers want,” Microsoft said in its blog post.
