search partnership

Yahoo Inc. believes a lot of its good work has been overlooked by investors and the media so it's spending more than $100 million to get the word out to consumers directly.

The money is going toward the Internet company's most expensive marketing campaign since Stanford University graduate students Jerry Yang and David Filo started Yahoo's Web site 15 years ago. Yahoo provided a peek at the 15-month blitz Tuesday in New York.

Before the dust even settles on the news that Microsoft and Yahoo will partner on Internet searches and advertising, the U.S. government has announced plans to scrutinize the deal. Sen. Herb Kohl (D-Wis.) said the Senate Judiciary Committee Subcommittee on Antitrust, Competition Policy, and Consumer Rights will investigate. He is chairman of the subcommittee.
