The Jonas Brothers (commonly abbreviated as JB) were an American pop rock group. Formed in 2005, they gained popularity from their appearances on the Disney Channel children's television network. They consist of three brothers from Wyckoff, New Jersey; Paul Kevin Jonas II, Joseph Adam Jonas, and Nicholas Jerry Jonas. In the summer of 2008 they starred in the Disney Channel Original Movie Camp Rock and its sequel, Camp Rock 2: The Final Jam. They also starred as Kevin, Joe, and Nick Lucas, the band JONAS, in their own Disney Channel series JONAS, which was later re-branded for its second season as Jonas L.A. The show was eventually cancelled after two seasons. The band released four albums: It's About Time (2006), Jonas Brothers (2007), A Little Bit Longer (2008), and Lines, Vines and Trying Times (2009).

In 2008, the group was nominated for the Best New Artist award at the 51st Grammy Awards and won the award for Breakthrough Artist at the American Music Awards. As of May 2009, before the release of Lines, Vines and Trying Times, they had sold over eight million albums worldwide. After a hiatus during 2010 and 2011 to pursue solo-projects, the group reconciled in 2012 to record a new album, which was cancelled following their break-up on October 29, 2013.

They have sold over 17 million albums worldwide.
