YouTube launches new iPhone app ahead of iOS 6 release:
For YouTube, breaking with Apple meant a chance to bring the slick, modern experience it built for Android devices to hundreds of millions of current and future iPhone owners. YouTube had little control over the app that bore its name for the past five years; Apple built the app itself according to YouTube’s instructions but updated it infrequently. The ban on advertising made it difficult to access copyrighted content inside the app; many a music fan went looking for a Lady Gaga video over the years on iOS and came up empty.
