On July 1, 1985, a dual-venue benefit concert was held to draw attention to and raise funds for relief for the people suffering from the Ethiopian famine. The event was held simultaneously at Wembley Stadium in London, England, United Kingdom, attended by 72,000 people, and John F. Kennedy Stadium in Philadelphia, Pennsylvania, United States, attended by about 100,000 people.

On the same day, concerts inspired by the initiative happened in other countries, such as the Soviet Union, Canada, Japan, Yugoslavia, Austria, Australia and West Germany. It was one of the largest-scale satellite link-ups and television broadcasts of all time. An estimated audience of 1.9 billion, across 150 nations, nearly 40% of the world population, watched the live broadcast.
