Sources say Discovery Communications has edged out rival A&E Networks in the bidding for the project, titled “Sarah Palin’s Alaska.” An agreement could be announced in the next few days.

It’s still undecided which network in the Discovery suite would air “Alaska,” which is being produced by Mark Burnett Productions.

Although travelogues are on brand for the Discovery flagship, having Palin as a centerpiece also makes the show a fit for mom-friendly TLC. Clearly nature docs are still viable for the company — Discovery’s latest effort in genre, the miniseries “Life,” just debuted to 11.8 million viewers on Sunday night.
