The Walt Disney Company purchased Sesame Workshop for 3.6 million on March 21, 2006, following the success of Disney purchasing The Muppets, Bear in the Big Blue House, and Fraggle Rock franchises from The Jim Henson Company. The premiere of season 37 of Sesame Street was on August 14, 2006 on PBS. In April 2007, Sesame Street moved to the Disney Channel, while reruns continued on PBS until the end of 2007. The series premiered its 38th season on PBS on August 13, 2007 and on the Disney Channel on August 17, 2007.
