In June 1996, WKRC-TV and WCPO-TV traded networks, leaving WLWT as the only Cincinnati television station to never change its affiliation. Additionally, the purchase by Hearst made WLWT sister stations with Hearst flagship stations WTAE-TV in Pittsburgh and WBAL-TV in Baltimore, leading to all three stations to have a friendly rivalry with each other during the NFL season, as all three local NFL teams (Cincinnati Bengals, Pittsburgh Steelers, Baltimore Ravens) are division rivals in the AFC North. WLWT briefly aired UPN programming as a secondary affiliation during the early morning hours on weekends at certain points in 1998 (the network was then limited to a six-hour weekly schedule), after that netlet was displaced from its previous affiliate WSTR-TV (channel 64) by The WB. The expected lower ratings in a late night time slot on WLWT (along with low promotion of UPN programming outside of Star Trek: Voyager) saw UPN capitulate and affiliate with former WB affiliate WBQC-CA (channel 25) in September 1998 as the network expanded to a ten-hour schedule that month which would have likely saw program rejections from WLWT due to lack of schedule room. In June 1999, WLWT moved its studios from Crosley Square to the Mount Auburn neighborhood, in a building that once served as the corporate headquarters of WKRC-TV's founding owners Taft Broadcasting. This is because after abandoning local non-news program production, the station found that Crosley Square, with its two-story ballrooms and basement newsroom, was built more for live entertainment broadcasts than a news operation. In June 2007, WLWT announced that it would partner with WLW (AM) to provide news and weather for the radio station. As a consequence, WLWT's news and weather updates were heard nationwide on WLW's XM Satellite Radio channel, at channel 173; the agreement with XM ended in the summer of 2008. WLWT and WLW shared news and weather operations for years while both were owned by Crosley Broadcasting, but eventual separate ownerships of the two stations (WLWT to Argyle, then Hearst Television; WLW to Clear Channel) led to WLW radio using the resources of WKRC-TV for several years until the renewed partnership with its former television sister. The modern WLW-WLWT partnership ended on March 31, 2010; WLWT currently provides news and weather to several Cincinnati radio stations. The transmission tower seen at the beginning of the 1978–1982 CBS sitcom WKRP in Cincinnati actually belonged to WLWT—it was located at
