Google and Amazon are burying the hatchet to better serve users of their respective streaming video platforms, the companies announced this morning. In the months ahead, the official YouTube app will come to Amazon Fire TV devices and Fire TV Edition smart TVs, while the Prime Video app will come to Chromecast and other devices with Chromecast built-in.

Prime Video will also become broadly available across the Android TV partner ecosystem, and YouTube’s sister apps — YouTube TV and YouTube Kids — will come to Fire TV later in the year.
