Live Aid was a dual venue concert that was held on 13 July 1985. The event was organized by Bob Geldof and Midge Ure to raise funds for relief of the ongoing Ethiopian famine. Billed as the ''Global Jukebox'', the event was held simultaneously in Wembley Stadium in London, England, United Kingdom (attended by 72,000 people) and John F. Kennedy Stadium in Philadelphia, Pennsylvania, United States (attended by about 100,000 people). On the same day, concerts inspired by the initiative happened in other countries, such as Australia and 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, watched the live broadcast.
The 1985 Live Aid concert was conceived as a follow on to another Geldof/Goldsmith project, the successful charity single ''Do They Know It's Christmas?''. 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. Bob Geldof saw the report, and called Midge Ure from Ultravox, and together they quickly co-wrote the song, ''Do They Know It's Christmas?'' in the hope of raising money for famine relief. Geldof then contacted colleagues in the music industry and persuaded them to record the single under the title 'Band Aid' for free. Performed by a collection of British and Irish musicians, the song was released on 7 December 1984 and became the fastest selling single ever in Britain and raised £8 million, rather than the £70,000 Geldof had expected. Geldof then set his sights on staging a huge concert to raise further funds.
The concert grew in scope, as more acts were added on both sides of the Atlantic. As a charity fundraiser, the concert far exceeded its goals: on a television programme in 2001, one of the organizers stated that while initially it had been hoped that Live Aid would raise £1 million with the help of Wembley tickets costing £25.00 each, the final figure was £150 million (approx. $283.6 million). Partly in recognition of the Live Aid effort, Bob Geldof received an honorary knighthood. Music promoter Harvey Goldsmith was also instrumental in bringing the plans of Geldof and Ure to fruition.
