WHA-TV in Madison first signed on May 3, 1954. It was the first public television station in Wisconsin and remained the only one until WMVS (Milwaukee Public Television) signed on in 1957.
1971–1988
In 1971, the Wisconsin state legislature created the Wisconsin Educational Communications Board, activating five stations as satellites of WHA-TV during the 1970s - WPNE/Green Bay in 1972; WHWC/Menomonie and WHLA/La Crosse in 1973; WHRM/Wausau in 1975 and WLEF/Park Falls in 1977. Though united as a network, WHA-TV and the other stations would employ their respective call signs for on-air branding until the mid-1980s.

On November 4, 2019, the "Wisconsin Public Television" brand was retired and replaced by "PBS Wisconsin," reflecting the statewide network's connections to the national PBS brand.
