What was the name of McDonald's 1984 advertising campaign honoring the 1984 Summer Olympics?

McDonald's called its 1984 Olympic advertising promotion “When the U.S. Wins, You Win.”

The promotion was tied to the 1984 Summer Olympics in Los Angeles, where McDonald's was a major sponsor. Customers received game pieces or promotional materials connected to Olympic events, with prizes linked to United States victories.

The campaign became famous because the Soviet Union and several other Eastern Bloc countries boycotted the Los Angeles Games. The reduced competition meant that the United States won many medals, increasing the number of prizes McDonald's had to honor under the promotion.

The event is often remembered as a marketing mishap rather than simply an Olympic sponsorship. McDonald's had expected a normal competitive medal distribution, but the boycott changed the results dramatically. The episode remains one of the best-known examples of an unforeseen event affecting a fast-food promotion.
