On there website it says they serve 100,000,000 visits per month. That's 1,200,000,000 visits per year. Assuming 5 pageviews per visit: 6,000,000,000 page views per year. Demand media had revenues of 325,000,000 in 2011 That works out at 54.16$ CPM To me it sounds insane, nearly 1 million$ per day in advertising revenue, and most of them sites have adsense on them.
