National Geographic Partners chairman Gary Knell outlines his vision of the growth opportunities ahead for the gold-plated brand as it and other 21st Century Fox assets transition to Disney’s control. Knell also gives a final salute to Fox, calling the parting “bittersweet” and praising the Murdochs for being good stewards of the brand. If it weren’t for Nat Geo’s move into television more than 20 years ago with Fox, “there’s a good chance National Geographic wouldn’t be around today,” Knell says.
