AdSense Premium

If you're into upgrades, Google is now offering

"AdSense Premium", which is CPC based and, for the time

being, offers less flexibility in terms of ad sizes -- only

banners and skyscrapers are currently available. You can
apply using existing Adsense accounts, or you can request

a new account. Applicants are usually notified within a day
as to whether they've been accepted for the program.

Here's the thing you need to know: Google has no

strict criteria for acceptance into the AdSense program,
and Ad Sense doesn't hit you with a minimum traffic

requirement. The only criteria they're really sticky about is
the standard "acceptable content" requirements, and that's

pretty standard almost anywhere.
