Probably not after tac, though I guess it depends on what you call fat margins. Rumors are google pays apple 75% for their search deal. My suspicion is google keep under 30% of mobile ad spend too.
But we can reasonably expect they pay something (cite: the Mozilla deal = $300M in 2013) and iOS is worth a lot more than that.
Given the economics and the relationship between Apple and Google it doesn't seem an impossible number.
It would be great if you could provide a better number rather than that somewhat critical comment.
Exactly right, even if Oracle is including mobile ads the margins make no sense
