Comcast announced a brand new service called “Stream” this weekend to bring live TV to your devices. Stream includes HBO and all the major stations along with cloud DVR for just $15 per month, though there is a catch.

Comcast Stream is only available for Xfinity Internet subscribers, and you can only watch live TV from inside your own home. It will also be limited to Boston when it launches this summer. Eventually, it will spread to Chicago and Seattle before expanding across Comcast’s entire network by early next year.

You can sign up online to find out if you qualify for Stream. After that, all you need to do is download the Xfinity TV app and you should be good to go.

The new service is a clear attempt to bring in cord-cutters who are tired of paying for traditional cable. Assuming you already use Comcast’s Internet, this seems like a pretty great deal considering you can pay the same $15 per month for HBO Now or try Stream and get a whole lot more. Hopefully we’ll get a chance to try it out before too long.
