I would think that this thought process... that Google might want to expand it's advertising base, and also break into a different genre, would be a pretty... well interesting move, if not a fantastic opportunity to do two things:

2) Allow them to experiment with yet another new way of doing business outside of the search engine, Android and Chrome.
Yeah, very very different though from an entertainment only company like Disney or Steam.
