It's hard to believe these days, but at one time Burger Chef was the number two fast-food burger chain in the United States, second only to McDonald's (NYSE: MCD). Its easy to forget as well that Burger Chef pioneered many of the things that its rivals became known for, including flame-broiled burgers, value combo meals, and a works bar that allowed customers to dress burgers their way.

Burger Chef had cartoon mascots, including the Burger Chef (voiced by Paul Winchell) and his sidekick Jeff, Count Fangburger, Burgerilla, Cackleburger and others. In the early 1970s, the company also offered a "Funmeal" with specially printed packaging and accompanying toys or puzzles. Burger Chef sued McDonald's after it introduced the Happy Meal in 1978, but ultimately lost.

Burger Chef offered a fish sandwich and fried apple or cherry pies. Some locations offered tale-side service, and others had windows that allowed customers to watch sandwiches being made. Burger Chef was also an early adopter of the media tie-in, with the Batman television series and the original Star Wars movie in the 1970s.

This post is part of a series on some of the most memorable companies that have disappeared.

The history of General Foods can be traced back to the Postum Cereal Company, founded by Charles William Post, inventor of Postum and Grape Nuts, in 1895. Wall Street player E.F. Hutton in time became the chairman, and he initiated a series of acquisitions beginning in 1925: Jell-O, Minute Tapioca, Log Cabin, Hellmann, Calumet Baking Powder, and Birdseye. It was after the Birdseye acquisition in 1929 that the food conglomerate became General Foods.

Among General Foods' many product offerings were Sanka decaffinated coffee and the astronaut's favorite, Tang. General Foods also continued to make acquisitions, including the makers of Kool-Aid in 1953, the Burger Chef restaurant chain in 1968, and Oscar Mayer in 1981.

But late in 1985, General Foods was itself acquired by Philip Morris Cos., which later became Altria Group (NYSE: MO), in the largest non-oil acquisition to date. When Philip Morris acquired Kraft in 1988, the two food companies were merged. In 2007, Altria spun off Kraft Foods (NYSE: KFT), which now owns such former General Foods brands as Jell-O, Kool-Aid, and Maxwell House coffee. And it was announced in late 2007 that Post Cereals, including Grape Nuts, would be sold to Ralcorp Holdings (NYSE: RAH).
