The series has been nominated for a Primetime Emmy Award for Outstanding Children's Program from 2007 through 2010. Hannah Montana: The Movie was released in theaters on April 10, 2009. The third season of the series premiered on November 2, 2008 and ended on March 14, 2010. The show was renewed for the fourth and final season, which started production on January 18, 2010, and ended production on May 14, 2010. The final season premiered on July 11, 2010, and became the last Disney Channel sitcom to transition from standard definition to high definition in the process. The fourth season of Hannah Montana was promoted as Hannah Montana Forever. The one hour series finale aired on January 16, 2011.
In December 2006, Disney announced plans to release Hannah Montana products, including clothing, jewelry, apparel, and dolls, at selected stores. Play Along Toys released the Hannah Montana fashion dolls, singing dolls, Miley Stewart doll, and other merchandise in August 2007. More Hannah dolls were released in November, along with Oliver, Lilly, and later Jake Ryan dolls. They became one of the most popular Christmas toys in 2007.
According to the Daily Dispatch, the TV series held a global audience of 200e million viewers in 2008. If Miley’s viewers were a country, they would be the fifth largest population in the world – just ahead of Brazil.  By February 2008, the Hannah Montana franchise had become so important that Disney convened an 80-person, all-platform international meeting to discuss Hannah Montana's future.  All Disney business segments were represented at the meeting.
The theme song for Hannah Montana is The Best of Both Worlds written by Matthew Gerrard and Robbie Nevil, produced by Gerrard and performed by Miley Cyrus (as Hannah Montana). John Carta, who also composed the music cues to signify scene changes and commercial breaks for the first season, composed the music for the song. The song's lyrics describe the basic premise of the television series.
