As for the YouTube app, debuted by default in the first iPhone version in 2007 and appearing ever since, Apple justifies its liquidation with the license end. The users will be able to reach the popular videohosting on the browser Safari, or download a special app from the App Store.
Many users felt uncomfortable with YouTube app far before its closing down and have switched to m.youtube.com on Safari. Besides, Google is actively developing its own YouTube app for the App Store. However, the search giant may still lose part of its searching audience on Apple devices.
