Yahoo has reached a deal to hire Google to handle some of its advertising sales that Yahoo says will increase its revenue by at least 800 million dollars during the first year of the agreement.
Yahoo's advertising partnership with Google would not start before late September of this year at the earliest because both Yahoo and Google have voluntarily agreed to wait at least that long to allow a government review.
Under the deal, either Yahoo or Google could end it if there is a change in the control of Yahoo. If it happens within 24 months, Yahoo would be required to pay Google a termination fee that could be as much as 250 million dollars.
