In a move intended to promote its own Prime Video service, Amazon is banning the sale of competing video streaming devices on its online store, Bloomberg reports. An email recently sent to its marketplace sellers noted that it will no longer be selling Apple TV and Google Chromecast devices; no new listings will be permitted and existing listings will be removed on October 29. In the email, Amazon stated that “It’s important that the streaming media players we sell interact well with Prime Video in order to avoid customer confusion.” Prime Video is not supported on the Apple TV and Google Chromecast, although of course Amazon’s own Fire TV supports the service, as do other platforms by Roku, Microsoft, and Sony, which will continue to be permitted for sale on Amazon. With the new Apple TV supporting third-party apps, it’s unclear whether Amazon may opt to build a Prime Video app for Apple’s new set-top box platform. Apple’s new Apple TV is set for release this month, but no firm release date has been announced yet.
