McDonald’s was a main sponsor of the 1984 Summer Olympics.
McDonalds ran a promotional game called "When The US Wins, You Win" where customers scratched off a ticket and if the US won that event then they would be given a free menu item. The company lost millions of dollars when the Soviet boycott let the US athletes fare better than they otherwise would have.
This was parodied in the Simpsons episode, Lisa's First Word. In this episode Krusty runs a promotion where Krusty Burger is the "Official Meat-Flavored Sandwich of the 1984 Olympics". In the promotion, scratch off tickets are given out and if the US wins the event indicated on the ticket then the holder of the ticket wins a free burger. The promotion however was rigged so only events where communists usually win are given out. After the Soviet Union boycotts the games Krusty loses 44 million dollars, causing him to angrily inform viewers, "I, personally, am going to spit in every fiftieth burger!" (Homer: "I like those odds!")
