Actually you just need traffic, a shit load of quality traffic. Once you break thru the 1 million UV/ Month [33,000UV/day] you get into the premium CPM rates. Fed media is just one of a few premium cpm networks.

Or for example, if you had finanical industry type autoblogs you can run a openX adserver & sell your own ads for premium rates & cut out the 50+% the cpm network is stealing. Its not hard to get $10-30CPM in the financial services, if you have the traffic.

There are quite a few celb autoblogs getting these CPM rates & traffic [just a bit under], but you have to have the traffic. Porn traffic trading systems & autoblogs are a killer compo.
