Microsoft Corp. signed Justice Department assistant attorney general Joel Klein to a three-year, $350 million endorsement deal Monday. Klein, who will appear in Microsoft TV and print ads, joins a growing list of high-profile government personalities who have signed endorsement deals with the software giant, including solicitor general Seth Waxman, FTC chair Robert Pitofsky and federal judge Thomas Penfield Jackson. 'We are thrilled to have a big-time celebrity like Joel Klein endorsing our products,' Microsofts Bill Gates said. 'This highly recognizable figure should help greatly increase public awareness of Microsoft.' Said Klein: 'I am very excited to lend my image and name to Microsoft, Americas Software People. The company has long impressed me with the high quality of its products and its fair, non-monopolistic business practices.' Klein then issued a cease-and-desist order against Apple Computer for anti-competitive pricing tactics, deceptive advertising, and unlawful employment of underage slave labor.
