Most of the most successful corporations/businesses have vision/innovation to begin with, they do create useful things that people didn't know they wanted but once they see it they do. After a while though, the business gets big enough that no new innovation can actually move the needle on the businesses revenues, the people at those companies who do have ideas are better off getting paid well for some period of time and then leaving to make it themselves. That's the stage google is in more or less, innovation won't move their bottom line very much so they're trying to extract as much as possible from their existing businesses, which basically means as many ads as possible in as many places as possible.
