Tide has a terrific set of brand values. Tide invokes home, family and cleanliness. It also has a whopping market share. So why not associate other things I should use that Proctor and Gamble creates? For example, a coupon spread with both Old Spice and Tide, with man’s clothes, saying “Why would you put clean clothes on a dirty body?”. Associate the two brands and I’m more likely to buy both.
