Candy Company Leaving Saatchi: In the latest blow for British advertising group Saatchi & Saatchi, Mars Inc., the maker of M&M;’s candies and Snickers chocolate bars, said it chose Omnicom Group Inc. subsidiary BBDO Worldwide Inc. as one of its three core international agencies. BBDO replaces Saatchi & Saatchi’s Bates Worldwide Inc. unit. Mars said its two other agencies, DMB&B; and Grey Advertising Inc., remain. Mars spokesman John Murray said the company’s annual worldwide billings are just under $1 billion. Saatchi & Saatchi has been trying to rebound from the confusion caused by the ouster of Maurice Saatchi as chairman in December and the loss of a string of top executives and some disgruntled clients.
