As a result of joining ABC, channel 26 became the second Tribune-owned station to switch to a "Big Three" network (Atlanta sister station WGNX, now owned by the Meredith Corporation as WGCL-TV, was set to affiliate with The WB at its launch, but joined CBS one month prior in December 1994 after WAGA-TV switched from CBS to Fox through a deal with New World Communications) and only the third "Big Three" station in its portfolio (along with KDAL-TV (now KDLH) in Duluth, Minnesota, a CBS affiliate that Tribune had owned from 1960 to 1970). From 1999—when Tribune sold CBS affiliate WGNX (now WGCL-TV) in Atlanta to the Meredith Corporation—until 2013, WGNO was the only Tribune-owned television station that was affiliated with a "Big Three" network (by 2007, the company's other 22 stations were, and remain, affiliates of either Fox, The CW or MyNetworkTV). However, Tribune's December 2013 acquisition of Local TV added eleven additional "Big Three" stations to its portfolio; the purchase also displaced WGNO/WNOL as the company's smallest television stations by market size, with the Fort Smith, Arkansas duopoly of CBS affiliate KFSM-TV and MyNetworkTV affiliate KXNW filling that role.
