Jonathan Tisch, chairman of Loews Hotels, is backing Walnut Hill Media, a new media media investment fund that will also get involved on the creative side. The New York-based firm will invest in traditional media (film, TV, etc.) as well as online media. Its initial investments are a bit of a mix: it’s made a “multi-million” dollar investment in Tribeca Enterprises, the parent of the Tribeca Film Festival, which has also done some interesting work in digital film distribution. Other Walnut Hill projects include a TV judge show and a co-production with PlumTV, a resort town TV network with some blue-chip backers. In addition to Tisch (whose family name adorns the arts school at NYU), principals at Walnut Hill include Jeffrey Stewart (also from Loews) and Jen Farley, previously of *CBS* News. Neither the size of the investments nor the size of the firm itself have been disclosed. Release.
