The Christophers are based in New York City. Their newsletter, "Christopher News Notes", is published 10 times a year. They have produced a weekly television show ("Christopher Closeup") since 1952, often featuring interviews with celebrities. Interviewees have included Bob Hope, Jack Benny, Ken Burns, Daniel Rodríguez, Andrew Weil, and Tim Russert. Other incarnations of the show have included dramatic features, with guest stars Don Ameche, James Cagney, and Ricardo Montalban, among others. The show was originally broadcast on ABC, but has since changed its name to "Christopher Closeup" and has been relegated to limited syndication by local cable channels. It also syndicates a weekly radio program of the same name.
