London, Mar 7 : Tickets for Take That's UK tour generated a whopping 12.8 million pounds in online resales in 2007 across the nation's 25 biggest sites, according to research firm Tixdaq.
The firm also reported that tickets for concerts by the boy band and Led Zeppelin were the most in demand on Internet auction sites last year.
Meanwhile, Led Zeppelin's reunion gig at London's O2 produced the highest average ticket price at 707.97 pounds despite measures to prevent resale.
Tixdaq monitors secondary ticket sales on the websites.
Tickets for Paul McCartney's gig at the BBC Electric Proms were the second most expensive at an average of 498.14 pounds per ticket, while third were tickets for Ireland's Electric Picnic festival, fetching an average of 360.96 pounds each.
Tixdaq spokesman Will Muirhead said secondary ticket exchanges had created a huge new market in the last couple of years.
"No wonder artists are concerned that they do not generally share in the proceeds," BBC quoted him, as saying.
