Yahoo and Google may go ahead with ad deal

Google and Yahoo's deal to let Google place some ads on Yahoo's search pages, which the Justice Department is reviewing, should be allowed with limits, the American Antitrust Institute said on Tuesday.

Because the search advertising market is already extremely concentrated with Google by far the dominant firm, the institute argued that consumers would be best served if No 2 Yahoo remained independent.

Google's market share of US web search widened to 63 percent in August, while Yahoo dropped to 19.6 percent and Microsoft slipped to 8.3 percent, according to comScore Inc.
