From the Hollywood Reporter:
Discovery Communications has finished its deal with the former Alaska governor for her reality show, with the company planning to air the series on its TLC channel.
As first reported in THR, Discovery Communications edged out rival A&E Networks for the show, with the remaining question being which of its suite of channels would air the program. Discovery Channel is considered the flagship brand, and certainly a home for travelogues, though the company felt Palin's appeal was better suited toward mom-friendly TLC. The network is best known for "Jon & Kate Plus Eight," and also airs "Cake Boss," "Little People, Big World" and "American Chopper."
