What name did McDonald's use for its hamburger-focused restaurant after the 1948 reorganization?

After the 1948 reorganization, the hamburger-focused restaurant used the name McDonald's Famous Hamburgers.

The McDonald brothers closed their original barbecue drive-in temporarily while they changed the menu and service method. When the restaurant reopened, it emphasized hamburgers, cheeseburgers, French fries, milkshakes, and faster counter service.

This repositioning was a major branding change because it moved the business away from the broad barbecue-drive-in identity. The simplified menu made the restaurant easier to operate and helped establish a recognizable product range.

Later corporate branding generally shortened the public-facing name to McDonald’s. That later name should not be confused with the specific post-reorganization title used by the brothers.
