Live Aid, a dual-venue benefit concert organised primarily by Dublin-born Bob Geldof, is held on July 13, 1985. The event is organised by Geldof and Midge Ure to raise funds for relief of the ongoing Ethiopian famine. Billed as the “global jukebox,” the event is held simultaneously at Wembley Stadium in London, England, (attended by 72,000 people) and John F. Kennedy Stadium in Philadelphia, Pennsylvania, (attended by about 100,000 people).

On the same day, concerts inspired by the initiative take place in other countries, such as the Soviet Union, Canada, Japan, Yugoslavia, Austria, Australia and West Germany. It was one of the largest-scale satellite link-ups and television broadcasts of all time. An estimated global audience of 1.9 billion, across 150 nations, watch the live broadcast. If accurate, this would be nearly 40% of the world population at the time.

In October 1984, images of millions of people starving to death in Ethiopia were shown in the UK in Michael Buerk‘s BBC News reports on the 1984 famine. The report shocks Britain, motivating its citizens to inundate relief agencies, such as Save the Children, with donations, and to bring the world’s attention to the crisis in Ethiopia. Bob Geldof also sees the report, and calls Midge Ure from Ultravox, and together they quickly co-write the song, “Do They Know It’s Christmas?” in the hope of raising money for famine relief. Geldof then contacts colleagues in the music industry and persuades them to record the single under the title “Band Aid” for free. On November 25, 1984, the song is recorded at SARM West Studios in Notting Hill, London and is released four days later. It stays at number-one on the UK Singles Chart for five weeks, is Christmas number one, and becomes the fastest-selling single ever in Britain and raises £8 million, rather than the £70,000 Geldof and Ure had initially expected.

The 1985 Live Aid concert is conceived as a follow-up to the successful charity single. The idea to stage a charity concert to raise more funds for Ethiopia originally comes from Boy George, the lead singer of Culture Club. On Saturday, December 22, 1984, an impromptu gathering of some of the other artists from Band Aid join Culture Club on stage at the end of their concert at Wembley Stadium for an encore of “Do They Know It’s Christmas?” George is so overcome by the occasion he tells Geldof that they should consider organising a benefit concert.

The concert begins at noon at Wembley Stadium in London. It continues at John F. Kennedy Stadium in the United States, starting at 8:51 EDT. The overall concert continues for just over 16 hours, but since many artists’ performances are conducted simultaneously in Wembley and JFK, the total concert’s length is much longer.

Throughout the concerts, viewers are urged to donate money to the Live Aid cause. Three hundred phone lines are manned by the BBC, so that members of the public can make donations using their credit cards. The phone number and an address that viewers can send cheques to are repeated every twenty minutes.

The following day, news reports state that between £40 and £50 million had been raised. It is now estimated that around £150m has been raised for famine relief as a direct result of the concerts. Geldof mentions during the concert that the Republic of Ireland had given the most donations per capita, despite being in the threat of a serious economic recession at the time. The single largest donation comes from the Al Maktoum, who is part of the ruling family of Dubai, who donates £1M during a phone conversation with Geldof.
