The Sixty-Six Year Old Whopper

In 1953, Keith Kramer and Matthew Burns bought the rights to a special grill machine called the Insta-Broiler and named their restaurant Insta-Burger King. James McLamore and David Edgerton purchased one Insta-Burger in 1954, renamed it Burger King, and opened the first restaurant in Jacksonville, Florida. The duo came up with a gas grill that they called a "flame broiler," and eliminated the problems of the Insta-Broiler. The Burger King mascot was created in 1955 and the driver of that 1957 Oldsmobile (above) may have ordered the new Whopper for the first time. 

A full chronological history here including the origins of Mr. McLamore.

Dual Lane Faster Food

 

Rally's was founded in Louisville, Kentucky in 1985. In nearly a decade, Rally's was bought by CKE Restaurants, owners of Carl's Jr. and Hardee's then was sold to Checkers in 1999. With the merger, they emerged with the same menu. Generally, Rally's serves the Midwest and California while Checkers serves the Southeast and Northeast. Both use a unique double drive-thru system, based on their research that about half of all fast-food hamburger service is takeout or drive-thru. Except for five experimental locations, they offer no indoor seating but do provide seating outdoors. They have placed their emphasis on delivering a quality hamburger more inexpensively and quickly than its competitors. Their aggressive advertising campaigns shed light on a "Little place. Big taste." notably by The Big Buford burger. They gained notoriety with a couple of animated mascots, as well. There are about 900 locations as of 2019.
