TR50 which is MIT's list of world's innovative companies is out. These are companies who's innovations force other businesses to alter their strategic course.
So for 2012: alongside Facebook (web integration), Google (Android 4.0), Twitter (mobile app), Zynga (free games), Dropbox (sync files)
Only African company: Safaricom for deploying mobile health services on their network (Daktari-1525 etc). Good stuff.
