The program lasted about two and a half hours, and the global transmission was accomplished using four telecommunications satellites in geosynchronous orbit.
On June 25, 1967, the first global live satellite broadcast was held. It was a production of the collective name Our World (hrv. Naš svijet), with parts broadcast from as many as 14 countries (Australia, Austria, Canada, Denmark, France, Italy, Japan, Mexico, Spain, Sweden, Tunisia, Great Britain, USA and West Germany).
Some world-famous performers, such as the Beatles with the song All you need is love and Maria Callas, performed in the broadcasts. Pablo Picasso also took part, and it is estimated that between 400 and 700 million people watched the broadcast. A record was set for the size of television viewership because no live broadcast had been watched by so many people before. The program lasted about two and a half hours, and the global transmission was made using four telecommunications satellites in geosynchronous orbit (one of them was Intelsat I, also known as Early Bird, which became famous as the first telecommunications satellite in geosynchronous orbit).
Our World program began broadcasting from Canada and then continued in the other 14 countries, which agreed not to use any pre-recorded television material.
