Jonas Brothers

Pop music had its fair share of sibling pop acts - from The Jacksons to The Osmonds to Hanson. The 21st millennium's incarnation of these past acts, The Jonas Brothers - Kevin, J and Nick - took the music world by storm throughout 2007-08 with a heavy schedule of constant touring (they played seven major tours in a span of three years) and an abundance of clean-cut good looks. The brothers scored their first hit with the 2005 song "Mandy" and went on to star in 2008's "Camp Rock," a Disney Channel Original Movie that was expected to surpass the ratings of the monster success that was "High School Musical" (2006) before it even aired. Within a year, the threesome went from tween heartthrobs to mainstream phenomenon, known the world over and adored by people of all ages.
