Microsoft Mediaroom, first announced in 2007, was the home entertainment solution for the connected age. The IPTV service was designed to allow you to watch your TV shows on any internet-connected device in your house. Start a program on a TV in one room, stream it on your laptop in another and take it with you on your cell phone when you're on the go.

Mediaroom would integrate with your Xbox 360 as well, eliminating the need for an additional set-top box. And because it connected to the internet, there were rumors that the service would allow apps and email. But Microsoft hasn't been able to get the cable companies on board, so far only securing a limited agreement with the poorly distributed AT&T U-Verse network that doesn't allow laptop streaming. Mediaroom had a headstart at cracking the living room, but in the end Microsoft couldn't bring it home.
