What service-system name did McDonald’s use in its early branding before becoming a global restaurant chain?

McDonald’s used the name “Speedee Service System” for its early restaurant-service model.

Richard and Maurice McDonald developed the system after reorganizing their restaurant in San Bernardino, California, in 1948. It emphasized a limited menu, standardized preparation, assembly-line methods, and rapid customer service.

The system became an important part of the McDonald brothers’ early brand identity. Speedee, the chef mascot associated with it, visually communicated the promise of fast service before McDonald’s developed its later Golden Arches and character-heavy advertising.

The phrase is sometimes confused with the company’s later slogan-based branding. The Speedee Service System described how the restaurant operated; it was not the name of a menu item, a fictional town, or the later Golden Arches symbol.
