What was McDonald's original service-system brand name when the brothers reopened their restaurant in 1948?

McDonald's original service-system brand name was the Speedee Service System. Richard and Maurice McDonald introduced the system when they reopened their San Bernardino restaurant in 1948 after reorganizing its operation.

The brothers reduced the menu and standardized food preparation so orders could be produced quickly and consistently. This approach became an important precursor to the operating model later associated with fast-food chains worldwide.

The Speedee name was also used in the restaurant's early visual identity, including its mascot and signage. It linked the brand's name directly to speed rather than to the arches that later dominated McDonald's branding.

The system should not be confused with a later slogan or a single menu item. It described the restaurant's production and service method, and it helped establish the operational foundation on which the McDonald's brand grew.
