Google Search for Missing Yahoo Revenue Returns $1 Billion

Boy, that was fast. Yahoo’s (YHOO) limited two-week test of Google’s (GOOG) AdSense for Search service has yielded wondrous results. So wondrous, in fact, that we’re only a week into it and “people familiar with the matter” are already telling The Wall Street Journal that the trial may well lead to a broader outsourcing deal between the two companies.

Five bucks and a Yahoo Insta-Yodel! says the Net portal’s having another sit-down with Microsoft this week.

Anyway, by some estimates, a deal with Google would increase Yahoo’s cash flow by more than $1 billion a year. A nice little spike in revenue like that would certainly bolster Yahoo’s efforts to spur Microsoft (MSFT) into increasing its unsolicited buyout bid for the Internet pioneer. That being the case, why didn’t Yahoo forge such a partnership with Google last July when it was restructuring the company’s “ecosystem” and slaughtering sacred cows? Perhaps government approval was a concern?
