High Quality Content by WIKIPEDIA articles! The Z Channel was one of the first pay cable stations in the United States. Launched in 1974 from Los Angeles, California, this station was known for its devotion to the art of cinema due to the eclectic choice of films by the programming chief, Jerry Harvey. It also popularized the use of letterboxing on television, as well as showing `director`s cut` versions of films (which is a term popularized after Z Channel`s showing of Heaven`s Gate). Z Channel`s devotion to cinema and choice of rare and important films had an important influence on such directors as Robert Altman, Quentin Tarantino, and Jim Jarmusch. Z Channel was owned by Theta Cable (a division of TelePrompTer Corporation) which was acquired by Group W (Westinghouse) in 1981. Operations were located at Stanford and Nebraska in Santa Monica, California. In 1989, Z Channel faded to black and was replaced by SportsChannel Los Angeles.
