15. Miley Cyrus — $48,920,806

The Miley Cyrus/Hannah Montana franchise spans far beyond the music, with international book deals, appearances in major motion pictures, a line of branded products and a television program on the Disney Channel. The music itself is a crucial but small component to the revenue stream. Miley Cyrus performed in 57 sold-out venues in 2008, including the “Best of Both Worlds Tour,” which was also spun off into a Disney 3-D movie.
