What is the status of the marketplace?

Seems like adsense has been out for forever, what is up with all the other players?

Ad-sonar For a long time this used to be vaporware and when it finally did come out it payed peanuts.

bid-clix Seem very greedy and have very low payouts.

Overture You need a million impressions a day to get in, my friends who run large sites tell me Overture pays out about 3 times as much as google, but good luck getting in...

Seems kind of odd that yahoo and microsoft aren't trying to grab market share from google.

Besides Google, and Overture (if you qualify) there really are not any good options that I am aware of. Since most advertisers use these engines to advertise you will make more money with their ads than anybody else.
