The Computer Chronicles is an American half-hour television series, broadcast during 1983-2002 on Public Broadcasting Service (PBS) public television, which documented the rise of the personal computer from its infancy to the immense market at the turn of the 21st century. The series was created in 1983, by Stewart Cheifet (later co-host), then the station manager of the College of San Mateo's KCSM-TV (which co-produced the show with Harrisburg, PA's WITF-TV), initially broadcast as a local weekly series. It became a national series on PBS from fall 1983. Jim Warren was its founding host for its 1981-1982 season. It aired continuously from 1981 to 2002 with Cheifet co-hosting most of its later seasons. Gary Kildall served as co-host for six years (1983 to 1990) providing insights and commentary on products as well as discussions on the future of the ever-expanding personal computer sphere.
