Manhattan Cable Public Access TV required one person to sign up  as responsible for coordinating the show, arranging for other artists to produce programs and getting tapes delivered one week in advance. Reruns were permitted after 13 weeks of original programming. In practice the coordinator would also raise money for the show ie apply for grants from the Media Bureau or NYSCA (no kickstarter in pre-digital days), design and print schedules and contact the press. For more details, see  below for "Instructions to Producers" and "Tools"; see Press for latest and archival reviews/articles.
