The station signed on April 23, 1959, as WCHU (for Champaign–
Urbana). It was an
NBC affiliate and aired an
analog signal on UHF channel 33. It was owned by Plains Television Partners and was a
low-power, full-time satellite of Springfield's WICS. The WCHU signal traveled about from a transmitter at its studios atop the
Inman Hotel in Downtown Champaign. However, getting a decent signal from Springfield ( west of Champaign) was usually hit-or-miss at best. Plains Television had to build a microwave tower in Northwestern Champaign to send the WICS signal to the WCHU studios. With a more reliable signal, the station began a more routine schedule on September 14. It began broadcasting in
color the next year. In July 1960, Plains Television Partners bought WDAN-TV in
Danville. That station had debuted on December 19, 1953, as a low-powered ABC affiliate broadcasting on channel 24 with a signal radiating about from its transmitter. WDAN was owned by the
Gannett Company along with the
Danville Commercial-News newspaper and
WDAN radio (1490 AM). After the sale, Plains Television changed WDAN-TV's call letters to WICD (for "WICS Danville";
Federal Communications Commission [FCC] regulations at the time required separately-owned stations to use different call signs, and the
Commercial-News retained WDAN radio) and made it a full repeater of WCHU. From 1960 until 1967, WCHU/WICD aired some locally originated programs from the WCHU studios in Champaign. However, WICD's transmitter was not capable of broadcasting local programming in color. In June 1966, Plains Television announced WCHU and WICD would merge into a single full-power station broadcasting on channel 15. It would operate under WCHU's license and studios at the Inman Hotel in Champaign, but use the WICD call letters—whose meaning was now altered to mean "WICS Champaign–Danville". The new station would broadcast at a million
watts from the tallest tower in Illinois, at . The new station was to have gone on-air in January 1967, but an ice storm toppled the tower. It was eventually rebuilt and the new WICD went on-air in July. However, there are unconfirmed reports of a delay in the final paperwork for the revamped station. According to some reports, it may have still been using the WCHU call letters when it signed on at full power for the first time. The station moved from the Inman Hotel to its current studio facility on Country Fair Drive in 1978. In 1986, Plains Television sold WICS to
Guy Gannett Broadcasting (no relation to the much larger Gannett Company), but retained WICD. The two stations operated as a regional network simulcasting most network and syndicated programming. This arrangement nearly brought down WICD, even though it was a very prosperous period for NBC as a whole. For much of the 1980s it looked like channel 15 would revert to being a full-time satellite of WICS. In 1994, Plains Television sold WICD to Guy Gannett, who pumped significant resources into the station, particularly its news department. Guy Gannett then sold most of its television properties, including WICD/WICS, to the
Sinclair Broadcast Group in 1999. Soon after Sinclair took over, it turned around and announced it was selling WICS/WICD as well as
KGAN in
Cedar Rapids, Iowa to Sunrise Television. However, the FCC did not allow Sunrise to buy WICD/WICS due to Sunrise's ownership structure.
Hicks, Muse, Tate & Furst (HMTF), an investment firm controlled by then-
Texas Rangers and
Dallas Stars owner
Tom Hicks, owned a large block of Sunrise stock. HMTF is majority stockholder of the
LIN TV Corporation, then-owner of
WAND in Decatur. The FCC ruled HMTF held enough stock in Sunrise that an acquisition of WICD/WICS would result in a
duopoly between two of the four highest-rated stations in the market, which is forbidden by FCC rules. Sinclair subsequently withdrew the offer to sell the three stations in 2000. The station's 46-year affiliation with NBC ended on September 5, 2005, when, as part of a larger national deal between LIN TV and NBC that also involved
WDTN in
Dayton, Ohio (who swapped affiliations with WICS/WICD's Dayton sister station
WKEF the year before), WICD and WICS swapped affiliations with WAND and became ABC affiliates. With this switch, WICD replaced WAND as the default ABC affiliate for the Illinois side of the
Terre Haute, Indiana, market, which had not had an ABC affiliate of its own since longtime affiliate
WBAK-TV switched to Fox in 1995. The network swap actually improved reception for ABC programming on the Illinois side of the market. WICD's transmitter is not far from the Indiana line, while WAND's transmitter in
Argenta is near the middle of the state. Due to contracts with satellite providers, for a long time WICS was the only ABC station in the market uplinked on the Champaign–Springfield–Decatur local feeds. However,
Dish Network's Champaign–Springfield–Decatur feed began airing WICD on February 23, 2013, alongside WICS. For the same reason, when Dish dropped
WRTV from
Indianapolis as the local ABC affiliate for the Terre Haute feed, it uplinked WICS rather than WICD. This ended at the start of the 2011–12 television season, when
WAWV-TV rejoined ABC. In March 2011, WICD added music video channel
TheCoolTV to its second
digital subchannel and
Comcast digital channel 807. On August 31, 2012, TheCoolTV was dropped from all Sinclair stations, including WICD. On
December 31, 2012, Sinclair closed on the purchase of the non-license assets of GOCOM's three television stations, WRSP/WCCU and sister station WBUI for approximately $25.6 million. Sinclair provides sales and other non-programming services to the stations pursuant to shared services and joint sales agreements. Both WRSP/WCCU and WBUI were initially operated from separate facilities from WICS/WICD. However, WCCU quickly moved its advertising sales operation from its location on South Neil Street/
U.S. 45 in Champaign into WICD's studios. Eventually, WRSP and WBUI also moved from their offices on Old Rochester Road in Springfield and were consolidated into WICS' facility. On March 11, 2025, it was reported that Sinclair (WICD Licensee,
LLC) would sell five TV stations, including WICD and WICS, to Rincon Broadcasting Group, led by Todd Parkin. The sale was approved by the FCC on July 1, and completed on July 9. ==News operation==
