Public-access stations are disappearing across the country, thanks (or no thanks) to the greed of cable companies, which want to employ set-aside channels for commercial purposes, and government officials, who would rather use the outlets' funding for purposes other than providing a voice to citizen producers. In Denver, however, the public-access concept is being given one more chance, and Deproduction, the company charged with reviving it, is a worthy choice. The task won't be easy; the previous overseer, Denver Community Television, left a massive mess behind. But the Deproduction folks are experienced producers with an impressive educational background, and their passion and sincerity are infectious. If any group can succeed at this difficult mission, they can.
