The Jonas Brothers' debut album, titled It's About Time, was originally released on August 8, 2006. It debuted at number 91 on the Billboard 200 chart and sold approximately 60,000 copies in its first week. Overall, the album achieved moderate success, eventually selling around 250,000 copies in the United States, but it was not until their later self-titled album in 2007 that they gained significant mainstream recognition.
