“Over 1 million sold” began appearing on McDonald’s signs as the company counted its hamburgers in the 1950s.
The phrase was an early version of the restaurant chain’s famous sales-count messaging. By displaying a growing number of hamburgers sold, McDonald’s turned customer volume into a visible proof point for the brand’s popularity and momentum.
The wording later changed as the total increased, eventually becoming associated with the much more famous “Over 99 billion served” signs. The changing number made the sign a living part of McDonald’s advertising rather than a fixed corporate slogan.
People often remember the later “billions served” wording and place it in the earliest period. The early “Over 1 million sold” claim belongs to the company’s initial expansion, when reaching one million hamburgers was itself a notable milestone.
