Karmelkorn

Karmelkorn is an American popcorn retailer. It was founded in 1929 in Casper, Wyoming, by Bill O'Sullivan. Initially, Karmelkorn stores sold popcorn and caramel corn out of downtown storefronts, but by the 1960s, the chain began operating in shopping malls. By 1982, the chain had 270 shops in 43 states.

In 1986, Dairy Queen's parent company IDQ (now part of Berkshire Hathaway) purchased the Karmelkorn chain. Dairy Queen began co-branding Karmelkorn with the Dairy Queen and Orange Julius brands.
