I think throughout their existence they tried hard to be more than that. If they settled to be just an advertising business, then easy, you become an equivalent of Lamar Advertising, you post an equivalent of billboards for over a hundred years, perhaps run a few servers and settle for that. An advertising company doesn't need to try to break into cloud computing business and do all these things that Google is actually trying to do (whatever the degree of success).
