However, it's worth noting that this only applies to Fire TV sets – an official YouTube app for the Echo show is not yet planned. No YouTube app is planned for Amazon's Fire tablets, but these devices can already access YouTube through their browser.
This should mark the end of a long, controversial relationship between Amazon and Google. For a while, Amazon refused to sell Google's Chromecast devices that directly compete with Amazon's own Fire TV products. Amazon also did not include Google Cast support in the Prime Video app, which made it virtually impossible to get Prime Video on larger screens when you use Google products. Google responded by supporting the YouTube apps on Fire TV and the Echo Show.
However, at the end of last year, Amazon started selling Google Chromecast devices, suggesting that business relationships were improving. And although the apps are not yet available, we know that they will come soon. It would be nice if YouTube were also available in the Echo Show, but at least Google and Amazon no longer seem to sabotage each other's streaming video devices.
