TV: GEICO Ad tribute
The amount of car insurance advertising on the airwaves sometimes borders on the ridiculous. In terms of marketing savvy, though, there's only one real winner. GEICO, the insurance company that spawned the popular GEICO gekko and GEICO cavemen, has long flooded TV with its commercials, many created by "The Martin Agency."
Some were stupid, some were forgettable, but all were played several hundred million times. Indeed, the cavemen were so popular that ABC is launching a sitcom with a similar premise (which marks one of the rare occasions when a TV commercial gets turned into a show).
