Elvis Presley's concert Aloha from Hawaii is broadcast live via satellite, and sets the record as the most watched broadcast by an individual entertainer in television history.

Elvis Aaron Presley was an American singer and actor. Referred to as the "King of Rock and Roll", he is widely regarded as one of the most significant cultural figures of the 20th century. Presley's sexually provocative performance style, combined with a mix of influences across color lines during a transformative era in race relations, brought both great success and initial controversy.

Aloha from Hawaii via Satellite is a concert starring American singer Elvis Presley that took place at the Honolulu International Center and was broadcast live via satellite to audiences in Asia and Oceania on January 14, 1973. The show was presented with a delay in Europe. In the United States, to avoid a programming conflict with Super Bowl VII and Elvis on Tour which was playing in cinemas at the time, NBC opted to air a ninety-minute television special of the concert on April 4.

A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Some communications satellites are in geostationary orbit 22,236 miles (35,785 km) above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. But most form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently.
