A new episode of Hannah Montana aired on Sunday, and the ratings were not great. According to the New York Daily News, Nielsen ratings fell 14% from the previous fresh episode, which aired just under two months earlier. Sunday's show was down 26% from the first new episode of the year which aired in January.
Part of the problem is that since there are not that many new episodes, Disney has to spread the episodes out over a long period. This causes interest to decline. Other people are speculating that new shows like "Wizards of Waverly Place," starring Selena Gomez are taking the spotlight away from Hannah.
