KIIN-TV in Iowa City, serving most of eastern Iowa, became the network's second affiliate in 1970. By 1977 the newly-renamed Iowa Public Broadcasting Network had eight full-power stations. The Iowa Public Television name was adopted in 1982. In 2003, it purchased KQCT-TV in Davenport, which repeated the programming of Quad Cities PBS station WQPT-TV in the Iowa side of the Quad Cities. The calls were changed to KQIN.
IPTV was originally run by the state's General Services Department before then-Gov. Terry E. Branstad signed a bill creating the Iowa Public Broadcasting Board on May 16, 1983. In 1986 IPTV became part of the state's Cultural Affairs Department, and on July 1, 1992, IPTV became part of the Iowa Department of Education.
Combined, the nine IPTV stations reach almost all of Iowa, plus portions of Illinois, Minnesota, Nebraska, South Dakota and Missouri.
