The US-Soviet Space Bridge was a series of experimental, international telecasts between Soviet and U.S. viewers, performed by group of communication enthusiasts during the late Cold War era.
The first space bridge was an arrangement between the Unuson Corporation and Gosteleradio of the USSR for the US Festival, sponsored by computer pioneer Steve Wozniak.
The participants in that space bridge could see each other, ask questions and receive answers, and also hold a musical dialogue.
The programs of the subsequent space bridges consisted not only of music-hall turns and greetings but also discussions on different subjects, in which prominent scientists, public figures, cosmonauts and journalists took part.
According to Pozner's book, Parting With Illusions, many U.S. TV companies did not want to purchase those space bridges.
