Buzby appeared in a series of television commercials with the catchphrase: "Make someone happy with a phone call". Buzby's voice was provided by Bernard Cribbins.
The campaign spawned many marketing items, such as toys, badges, a comic strip in TV Comic, and books, and lasted until well into the 1980s. British Telecom produced and sold a "Buzby" wrist watch with Buzby perched on the second hand. The watch had a blue strap.
