Hubba Bubba is a brand of bubble gum originally produced by Wm. Wrigley Jr. Company, a subsidiary of Mars, Incorporated, in the United States in 1979 but more recently produced in countries around the world. The bubble gum got its name by the phrase “Hubba Hubba” that World War II soldiers used to express approval.  The main gimmick used to promote the gum is that Hubba Bubba is less sticky than other brands of bubble gum and so burst bubbles are easier to peel from your skin. The first portions of Hubba Bubba were produced in the traditional bubble gum flavor often referred to as Original, but different flavors of gum have been produced around the world. Many, but not all, of these flavors are based on fruit. Hubba Bubba products also include many flavors of soda, bubble gum, and squeeze pouches.

The cowboy in the advert was played by Don Collier and it was filmed entirely in Australia. Don’s portrayal of ranch foreman Sam Butler in the highly acclaimed television western, The High Chaparral, still stands as one of his greatest characterizations to his legions of fans.  He was United States Marshal

Will Foreman in Outlaws, shopkeeper William Tompkins in The Young Riders, and the host of educational television’s The Desert Speaks.
