The Martha Stewart Show is moving to the Hallmark Channel in the fall. As part of the deal, Hallmark "will present exclusive original programming currently in development" at Martha Stewart Living Omnimedia, the company announced today. Look for a roster of holiday and prime-time specials, too. Stewart is spreading her brand all over the place; in addition to Hallmark, her company’s shows are on PBS (Everyday Food) and, as of March, ION (The Emeril Lagasse Show). Martha’s talk show will debut on Hallmark in September.
