In McDonald’s branding history, what was the name of the service system represented by the original mascot Speedee?

The original mascot Speedee represented McDonald’s Speedee Service System.

McDonald’s introduced the system in 1948, when the McDonald brothers redesigned their San Bernardino, California, restaurant around speed, consistency, and a limited menu. The approach used an assembly-line kitchen modeled partly on industrial production. It helped create the modern fast-food format that McDonald’s later made globally recognizable.

Speedee was depicted as a chef-like character and initially served as a visual symbol of quick service. The branding connected the mascot with the restaurant’s promise that customers would receive food rapidly and in a standardized form.

Speedee is sometimes confused with later McDonald’s characters such as Ronald McDonald, Grimace, or the Hamburglar. Those figures belonged to the later McDonaldland era, while Speedee represented the company’s earliest service concept and predates the Golden Arches’ mature branding.
