ADVERTISING

* Campbell Soup Co. said it is reviving its “M’m! M’m! Good!” slogan with a new advertising campaign as part of an effort to jump-start flagging sales of its mainstay product. The slogan, first developed in the 1930s, has not been used as a tagline on Campbell’s advertising for 16 years. The new campaign was developed by Omnicom Group Inc.’s BBDO.
