The TED library is massive. So massive that it has more than 1,700 TEDTalk video and audio clips. The content comes from people including business moguls to musicians to world-renowned educators. The official TED app has something informative for just about everyone. What the Android app has lacked is Chromecast support. That is until today. Version 2.3.1 of the TED app for Android brings Chromecast support. Now users can mirror TED content from their devices to televisions.
