'Break Google up' would mean you'd have: * an Office suite / enterprise company (Google Cloud + Docs + Gmail + Business) * a phone company (Android) * a search company (Google Search + Advertisement) * and a media company (Google Play Movies, Music, Books and YouTube) The names would probably become different in time, but you get the gist.

The biggest blow to Google wouldn't be to break it up into lots of small companies, you just need to separate the advertising business from everything else and you've effectively neutered the monopoly. Google's genius isn't in hiring the best engineers to providing a ton of services, it's in convincing people that they're not an advertising company, and that is where Facebook has been falling out of favor recently (I'm guessing that's why they bought Instagram, and why Google bought YouTube).
