Wrigley’s Gum
In 1892, Wrigley Jr. began packaging chewing gum with each can of baking powder. The chewing gum eventually became more popular than the baking powder and Wrigley’s reoriented the company to produce the gum.
Wrigley began using twins to market the classic Spearmint chewing gum in 1939, playing off the idea that you should “Double your pleasure, double your fun, with Doublemint Gum.” Since 1960, the commercials have featured twins (even some famous ones) chewing along to the upbeat Doublemint tune.
