I am struggling to think of examples of this - help?
What are some examples of ad campaigns where a character or concept is introduced that then takes on a life of its own until the original character or campaign is no longer even present? Someone was talking about the Charmin ass-bears, how they were introduced as a side gag as one part of a campaign, only to continue to take over to the point where the campaigns now exclusively focus on those bears’ children talking about their asses and TP.
What are some other examples of this phenomenon?
