Chicago-based Tribune Broadcasting acquired Channel 46 in late 1983, after which its call letters were changed once again on March 15, 1984, this time to WGNX; the new callsign reflected a connection with Tribune's Chicago flagship station, WGN-TV (whose own callsign refers to the slogan of the "Chicago Tribune", "World's Greatest Newspaper"). Airings of "The 700 Club" on the station were reduced to once per day, before the show was dropped altogether—until channel 46 acquired the local rights to the program again in 2007. Under Tribune ownership, the newly-rechristened WGNX significantly upgraded its programming, picking up more racier programs than those allowed to air on the station under CBN ownership. The station formed a news department on January 16, 1989, airing a 10 p.m. newscast on weeknights, alongside the Tribune-distributed syndicated newscast "Independent Network News".
