If anyone had any doubt that touring is where the money is in the music business, a quick look at the top Moneymakers for 2008 should hammer the point home.

Regardless of genre, retail sales or radio play, each of the 20 acts on Billboard's Moneymakers list toured in 2008. (Taylor Swift mostly opened for Brad Paisley but doesn't get credit for that revenue). For almost all of them, touring generated the most revenue. And in a year when recorded-music sales declined yet again, many earned more at the box office than ever before.
