Hannah Montana, also known as Hannah Montana Forever for the fourth season, is an American musical comedy series created by Michael Poryes, Rich Correll, and Barry O'Brien which focused on Miley Stewart (portrayed by Miley Cyrus), a teenager living a double life as an average schoolgirl by day and a famous recording artist Hannah Montana by night. It follows the day-to-day life of Miley, her brother and friends while also starring Cyrus' country singer father Billy Ray Cyrus as her dad. The series, produced by It's a Laugh Productions and Michael Poryes Productions, premiered on Disney Channel on March 24, 2006 and concluded on January 16, 2011 after airing four seasons and ninety-eight episodes. The soundtrack albums Hannah Montana (2006), Hannah Montana 2: Meet Miley Cyrus (2007), Hannah Montana 3 (2009), and Hannah Montana Forever (2010) were released to coincide with their respective seasons. In 2007, the series' success led to the Best of Both Worlds Tour, which visited North America. The following year, it was adapted into the 3D film Hannah Montana & Miley Cyrus: Best of Both Worlds Concert and its accompanying soundtrack. In 2009, the series' first feature film Hannah Montana: The Movie was released to commercial success, and was additionally promoted through its accompanying soundtrack. The show has additionally distributed all seasons to DVD. The series received generally favorable reviews from critics, and has been recognized as a "guilty pleasure" by several media outlets. The show's instant success is widely credited with the launch of Cyrus' career and her establishment as a teen idol. However, as she continued to develop an increasingly provocative image as the series progressed, the series has received criticism for appearing to be a negative influence on its younger audience.
