Show business elites joined U.N. Secretary-General Kofi Annan in Geneva and pop stars in London and the United States on Saturday for an 11-hour transatlantic concert that united music and the Internet to fight global poverty.

NetAid--organized by Cisco Systems, an Internet networking company, and the United Nations Development Program--was watched or heard by millions on television and radio and on a Web site that organizers hoped would attract additional millions.

The concert was staged in three venues and featured overlapping performances, starting at Wembley Stadium in London and later moving to the Palais des Nations, the home of the United Nations in Geneva, and finally to Giants Stadium here.

Musicians included the reunited English rock duo the Eurythmics, who opened the show in London, George Michael and Pete Townshend, Wyclef Jean of the Fugees, Bono of the Irish rock group U2, Sting, Sheryl Crow, singer Bryan Ferry, rap singer Puff Daddy and South African band Ladysmith Black Mambazo.

The NetAid Webcast sustained a few brownouts due to heavy usage in some areas, including parts of California and New York, but it generally avoided the kinds of capacity problems faced by the Victoria's Secret Webcast last February, when many people were unable to access the site because of congested lines.

Organizers said 60 countries aired the concert on TV and 132 nations did so on radio, a record.

Officials said exact figures on the number of people accessing the Webcast or donating funds via the Web site would be released later.
