Top 2000 quantcast site - 2+ million visitors - adsense revenue down to 65% of same period sept (record month) - purely content/community site - not selling anything.

Ecpm - down to 70% of Dec 2007 levels.
CTR - down to 0.45% from 0.5% Dec 2007 (90%)

It is the economy - and due to falling revenues - I've stopped all advertising on adwords.

I believe that online advertising will one area that is hardest hit in the recession - it is very easy to stop, and there are no obligations to continue on even a day to day basis, and due to the algorithms Google uses if one big advertiser pulls out - pricing for the remaining advertisers is automatically lowered.
