In the early 2000s, The Walt Disney Company found success with its pay television network Disney Channel, which had a pattern of original programming for a preadolescent audience that featured music. The fictional girl group The Cheetah Girls was made popular by the eponymous television film and found commercial success outside the movie, and Hilary Duff's music was used to cross-promote the series "Lizzie McGuire". Disney was able to sponsor concerts featuring music from the network and use their talent to build on the brands; Gary Marsh, the president of Disney Channels Worldwide, cited "Lizzie McGuire" as its "first success". The network believed the new series "Hannah Montana" could be marketed in a similar manner. Hollywood.com said the show could build on the success of Disney's television film "High School Musical", which also includes music. The sitcom would premiere two months after the movie.
