The concerts in London, New Jersey and Geneva featured performances by George Michael, David Bowie, Eurythmics, Sting, Sheryl Crow and dozens of other stars.

Promoters said their Webcasts of the shows were accessed 2,385,455 times during Saturday, a new record for the Internet.

However, they are declining to reveal how much money was raised by the three concerts.

"We're still working on the figures," a spokeswoman in London said on Tuesday. She added that final figures on how many users visited the NetAid site would not be available for a further week.

Organisers hope they will reach their target of one billion hits by the end of the year. A 'hit' is defined as each time an element of a Web page - such as a graphic or text - is downloaded onto a user's PC.

The actual physical attendance at the three concerts was fewer than 110,000, according to Kent Jenkins, a spokesman for NetAid sponsor Cisco Systems.

Although attendance at London's Wembley Stadium was good, reviewers commented on New Jersey's Giants Stadium being half-empty.

The shows also suffered from bad publicity in the US when original patrons Harry Belafonte and Danny Glover withdrew their support, claiming NetAid had been overwhelmed by corporate self-interest and United Nations bureaucracy.

But Mr Jenkins said the organisers wanted NetAid to be known for much more than just one night of music, adding the aim was to get the site known worldwide.

He said it was "more about getting people involved... driving them to the site [and] getting them to commit time" to various projects.
