Don't they host their own ads? Something I wish more websites would do instead of letting ad networks stomp all over the page with whatever Javascript/Flash/viruses they want.
It's not surprising that Facebook serves its own ads, considering that it's one of the top 2 digital ad networks by revenue in the US. Google does the same for its sites.
Facebook and Google have a duopoly on the online ad market, with a combined 60.9% market share. Amazon is #3 with just 7.6%.
