Google co-founder Sergey Brin agreeing with Eric Schmidt about the "immaterial" click fraud problem, on March 2 (Analyst Day):
We believe that's a small fraction... We think we're doing a good job on that.
On the Google Blog ("Press release? Nah, just blog it"):
Last February, Google was sued in Arkansas over what is commonly called click fraud....
Under the agreement with the plaintiffs...we will offer credits which can be used to purchase new advertising with Google....the total amount of credits, plus attorneys fees, will not exceed $90 million.
Ninety million bucks: a lot to you or me, immaterial to Google. It's just their funny way of telling all their mom-and-pop clients, "we care."
