A strange one - Google are experimenting by changing the familiar "Ads By Google" to "Ads By Goooooooooooogle".

Google look to have a strategy to extend and make as accessible as possible the AdSense program; they recently opened the doors to the millions of bloggers who were previously excluded from the program by a rule stating personal sites would not be allowed, and AdSense for search is also a fairly new addition, which allows site owners to earn income from Google searches made from their sites.
