Because YouTube pulls the plug on its old API, the video site doesn't work anymore on many Smart TVs from before 2012, Apple TVs from before 2010 and iOS devices running on iOS 6 or earlier versions.
Users of Sony and Panasonic Smart TVs and Blu-ray players from before 2012 and older versions of Apple TV can no longer watch YouTube videos, according to a page on the YouTube site. Also older versions of Google TV are out of luck.
Users on a device running iOS 6 or previous versions, like an old iPhone, iPad or iPod Touch can use YouTube with the Safari browser. By adding a shortcut to the home screen users can still view videos.
The reason YouTube no longer works on older devices is because Google pulls the plug on support of YouTube API V2. Google announced the change a year ago to give developers the opportunity to switch to the new API. However that year has passed and Youtube ceases support for the old API next Monday. It's unknown how many users are affected by the change.
