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 a worldwide coverage, which 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.
