Sold Documentaries On Public TV, Firms Get Ads

Hugh Downs is the former anchor of NBC's Today show, ABC's 20/20 and PBS's classical music show Live From Lincoln Center. For a fee, Vision Media of Boca Raton, Fla., offers to create documentaries hosted by Downs for play on public television stations, but the firm has produced no evidence that the segments featuring its clients have aired on public TV.
