Power Rangers is a long-running American entertainment and merchandising franchise built around a live action children's television series featuring teams of costumed heroes. Produced first by Saban Entertainment, later by BVS Entertainment, and currently by SCG Power Rangers LLC, the series took its initial premise and much of its footage from the Japanese tokusatsu Super Sentai franchise. Its first entry, Mighty Morphin Power Rangers, debuted on August 28, 1993, and helped launch the Fox Kids programming block of the 1990s, during which it catapulted into popular culture along with a line of action figures and other toys by Bandai.
Despite initial criticism for its action violence targeted to child audiences, the franchise has continued, and as of 2011 the show consists of 19 television seasons of 16 different series, and two theatrical films. In 2009, production of Power Rangers ceased and the last new series, Power Rangers RPM, ended on December 26, 2009. Beginning in January 2010, the original series was rebroadcast in lieu of a new series utilizing footage from the 2009 Super Sentai television series. On May 12, 2010, it was announced that Saban had bought back the rights to the franchise and has plans to premiere the 19th season with 43 new episodes on the Nickelodeon network.
