Facebook unveils advertisement targeting plan

NEW YORK - The online hangout Facebook said Tuesday it plans to help companies target their advertisements on the site based on what its users and their friends buy and do on the Internet.

As Web companies look to boost advertising revenue by offering to target ads to their users' hobbies, interests and behavior, Facebook's move could change the tone of the site and revive privacy complaints it faced last year.

Facebook Chief Executive Mark Zuckerberg, who founded the company three years ago, said marketers must respond to the changing nature of communication.

Yahoo officials defend actions in China in face of U.S. accusations

WASHINGTON - Yahoo Inc.'s chief executive and top lawyer on Tuesday defended their company's involvement in the jailing of a Chinese journalist. Irate lawmakers accused them of collaborating with an oppressive communist regime.
