isabotage3 writes to tell us that the top three search companies, Google, Microsoft, and Yahoo, have teamed up to create an alliance to combat click fraud
. The fact that these three bitter rivals can team up shows just how serious the industry has become about preserving the current online advertising boom that is currently underway. From the article: "Click fraud has attracted an increasing amount of attention amid class-action lawsuits and industry studies asserting advertisers have been collectively overcharged by more than $1 billion for bogus sales leads during the past four years. Google and Yahoo contend that those estimates are gross exaggerations generated by opportunistic lawyers and online advertising consultants hoping to cash in on the anxieties triggered by their calculations."
