Here's the scoop on Ding Dongs/Ring Dings.
Drake's Ring Dings
The company marketed the snacks on the East Coast as Big Wheels, to avoid confusion with the Ring Ding, a similar (and pre-existing) treat by Drake's Cakes. The names were consolidated in 1987, when a short-lived merger of Drake's with Hostess' parent company (then Continental Baking Company) briefly resolved the Ring Ding/Ding Dong conflict
. When the merged company broke up, however, Hostess was forced to cease, once again, using the Ding Dongs name in areas where Ring Dings were available. The compromise sound-alike name King Dons lasted until Interstate Bakeries Corporation, which had recently merged with Hostess' parent company, bought Drake's in 1998. The Hostess product was then sold under the name Ding Dongs throughout the United States, although it was still sold as the King Don in Canada.
