On a crude estimate, a video watched 75 million times could generate about $1.87 million, or £1.3 million. That amount of money generated by an advert depends on what country the viewer is in. In the United States, advertisers pay $20 to $35 to be seen by 1,000 people, while in the UK the figures are the same but in pounds, between £20 and £35 per thousand. It does not matter whether clips are put up by fans or by ITV because YouTube insists that their commercial exploitation remains under the control of the copyright owner. The most popular clip of Susan Boyle singing I Dreamed a Dream was put up by a fan using the nickname “BritainsSoTalented”. It has been seen 39.2 million times since it was uploaded on April 11.
