What was McDonald's original service system called when the chain launched its early branding?

McDonald's original service system was called the Speedee Service System.

Richard and Maurice McDonald developed the system at their San Bernardino, California, restaurant after redesigning operations around speed, limited choice, assembly-line preparation, and self-service. The approach helped establish the operating model later associated with modern fast food.

The name also shaped the company's early branding. Speedee, a chef-like mascot, represented the system in McDonald's first logo in 1948. Customers were being promised not simply hamburgers, but a consistent and rapid way to receive them.

The Speedee Service System predates Ray Kroc's role in expanding McDonald's as a franchise business. Kroc joined the story in the 1950s, while the McDonald brothers had already created the operational model and its early identity. The later Golden Arches and Ronald McDonald branding built on a foundation that initially centered on efficiency.
