Comcast and Amazon have announced a partnership that will bring Amazon Prime Video access to Comcast’s Xfinity X1 cable boxes. This will be the first time that Prime Video has been available through a cable box in the US. Remember that Amazon recently rebranded Amazon Video into Prime Video, so this doesn’t just mean that free content included with a Prime membership will be accessible. It also means that all of the Amazon Channels, such as HBO, Showtime, and Starz will also be accessible. That’s significant because being able to get these channels without a traditional TV subscription is a huge reason why so many people are dropping cable subscriptions, like Comacast Xfinity. Prime Video will arrive on Comcast’s devices later this year.
