Don Imus's longtime advertisers -- even those who stuck with him during the controversy over his controversial remarks about the Rutgers University women's basketball team -- are taking a wait-and-see approach before committing to his new show on cable network RFD-TV and ABC Radio, Advertising Age reported today (Monday). Most expressed lukewarm reactions when approached by the trade publication about the possibility of their advertising on the Imus show. A spokesman for General Motors, a longtime Imus sponsor, said that it wanted to evaluate the new show before committing to it. Matthew Warnecke, in charge of buying radio time for MediaCom, commented, "I don't know if any of my advertisers have come to me saying, 'We want to be involved.'"
