No, that's actually pretty divided, with them. I mean, Google has 35%, and Facebook about 20%, but Google is on the decline slightly, and there's a bunch of competitors, so if they start charging extortionate prices, someone will undercut them. And this is just US ad revenue, I don't have global figures on hand, so it's probably even less. So sure, Google has the most market share, but that's hardly a monopoly.Really? Because as far as I'm aware, Google has a monopoly on that market as well.
