|Live Aid was a dual-venue concert held on 13 July 1985, and an ongoing music-based fundraising initiative. The original event was organised 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 at 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 the successful charity single "Do They Know It's Christmas?" which was also the brainchild of Geldof and Ure. 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. On 25 November 1984, the song was recorded at Sarm West Studios in Notting Hill, London, and was released four days later. It stayed at number-one for five weeks in the UK, was Christmas number one, and became the fastest-selling single ever in Britain and raised £8 million, rather than the £70,000 Geldof and Ure had initially expected.
