In a sign that it doesn't take a car person to get a company's message out there, GM's executive director of advertising and marketing left the company for a VP job at Home Depot. Roger Adams joined GM in 1996 after leaving a similar post at Keebler. Yes, Keebler, as in Keebler elves. GM will not be replacing Adams and is content to leave an extra level of management empty as there are about three other VPs with similar titles still at GM. We can only hazard a guess at the total number of executives in the GM marketing department. Lots of light bulb jokes come to mind. But instead we'll just ask why they don't pick some employees with an automotive background.
