Our World was the first live multinational multi-satellite television production. National broadcasters from fourteen countries around the world, coordinated by the European Broadcasting Union (EBU), participated in the program. The two-hour event, which was broadcast on Sunday 25 June 1967 in twenty-four countries, had an estimated audience of 400 to 700 million people, the largest television audience up to that date. Four communications satellites were used to provide worldwide coverage. This broadcast was a technological milestone in television broadcasting. Creative artists, including opera singer Heather Harper, film director Franco Zeffirelli, conductor Leonard Bernstein, sculptor Alexander Calder and painter Joan Miró were invited to perform or appear in separate live segments, each of them produced by one of the participant broadcasters. The most famous segment is one from the United Kingdom starring the Beatles performing their song "All You Need Is Love" for the first time.
Planning
The project was conceived by British Broadcasting Corporation (BBC) producer Aubrey Singer. Due to the magnitude of the production, its coordination was transferred to the European Broadcasting Union (EBU), with Singer as the project's head. Four communications satellites were used to televise the show around the world. These geosynchronous orbit satellites included Intelsat I (known as "Early Bird") and Intelsat II F-3 ("Canary Bird"). Both satellites were positioned over different parts of the Atlantic Ocean. Intelsat II F-2 ("Lani Bird") and NASA's ATS-1 were positioned over different parts of the Pacific Ocean to complete global coverage. Nine ground stations were utilized to send and receive signals from the satellites. The EBU's Eurovision point-to-point communications network was used within that continent. These signals were monitored and manipulated by technical and production teams in 43 control rooms that linked North America, Europe, Tunisia, Japan and Australia in real time. The master control room for the broadcast was the TC1 studio control room at the BBC Television Centre in London. Contributions from North America, Japan and Australia were routed to London by the CBS Switching Center in New York. It was rented because none of the big-three American networks was directly involved with the broadcast. Contributions from continental Europe and Tunisia were routed to London by the EBU Centre in Brussels. These centres were also in charge of distributing the live master feed from London to the broadcasters in their assigned area. To illustrate the introductory segments, a large set was built at BBC's TC1 studio, which was operated by the TC2 studio control room. To solve language issues, each receiving broadcaster had its own narrator – such as Cliff Michelmore at BBC, or James Dibble at ABC – reading in their own language the script written by Antony Jay. Since the contributions from the participating broadcasters were in their native language, a team of interpreters located at BBC's TC2 studio provided simultaneous translation into English, French and German to the receiving broadcasters, where local commentators voiced-over in their own language the original sound from other broadcasters when in another language. It took 10 months and 10,000 technicians, producers and performers to bring everything together. The ground rules included that no politicians or heads of state could participate in the broadcast. In addition, everything had to be live, so no use of videotape or film was permitted. All participants had to have full knowledge of what was going to be included and the sole reason for including an item would be program balance, not geographical or political concerns. In the dress rehearsal, conducted the day before broadcast, the head of the production noticed that in violation of one of the ground rules, the Mexican broadcaster had pre-recorded their main segment. They included singers, dancers and a flock of white doves taking off right on cue and attempted to pass it off as live. Replicating that scene for the actual broadcast was impossible. So, it was decided to show some of the performers watching their taped performance live on monitors.
Participants Fourteen national broadcasters participated in the program, which was transmitted live to 24 countries, with an estimated audience between 400 and 700 million people. Eighteen national broadcasters were intended to participate, but those of the Eastern Bloc countries – Czechoslovakia, East Germany, Hungary, Poland and the Soviet Union – pulled out four days before the broadcast in protest of the Western nations' response to the Six-Day War. Due to this withdrawal, a request was made to the Danish broadcaster, which was not originally a participant, for a contribution.
Broadcast Each broadcaster had an explanatory pre-transmission introduction from their studios to their viewers – such as the introduction by Cliff Michelmore at BBC's TC5 studio in London for BBC1, the one by James Dibble at ABC's studio 23 in Sydney for ABC-TV and the interview to philosopher Marshall McLuhan at the television control room in Toronto for CBC Television – just before connecting to the live master feed from London at 7:00 p.m. GMT. The program was divided into six sections: the Opening, This Moment's World, The Crowded World, Aspiration to Physical Excellence, Aspiration to Artistic Excellence and The World Beyond. These sections were divided into live segments provided by the participating broadcasters. Just before The Crowded World section, another section was scheduled – The Hungry World. But, due to the withdrawal of the Eastern Bloc countries' segments, that section was eventually removed and its remaining segments were incorporated into The Crowded World section.
Opening The opening credits were accompanied by the "Our World theme" played by the Vienna Philharmonic and sung in seventeen different languages by the Vienna Boys' Choir. The program began with an introduction from the BBC's TC1 studio in London and went on attending the births of four children in the delivery rooms at Hokkaido University Hospital in Sapporo, Japan; at Aarhus University Hospital in Aarhus, Denmark; at Hospital de Obstetricia III in Mexico City, Mexico –reported by Pedro Ferriz–; and, at Charles Camsell Hospital in Edmonton, Canada – reported by the CBC's Libbie Christensen.
