Bloomberg News ranked artists based on the average secondary-market prices
for concert tour tickets for shows from Memorial Day to Labor Day 2013
in the U.S. and Canada.
The most popular tours were selected based on searches on
secondary-market ticket price aggregator TiqIQ. Average secondary-market
prices were determined by totaling the value of all tickets available
on the secondary market according to TiqIQ and dividing by the number of
tickets available on TiqIQ as of June 10. Figures are list prices. List
prices are volatile and typically change closer to concert dates.
