On February 1, 1995, the station changed its call letters to the current KQCA; it also became an affiliate of UPN, and changed its on-air branding to "Q 58" (a branding similar to KCRA's then-sister station, Fox affiliate KCPQ in Seattle, Washington, which it still uses to this day), barely missing the January 16 launch of the network (meaning viewers had to watch the network via KBHK-TV in San Francisco those first two weeks). On January 5, 1998, it swapped affiliations with KMAX-TV (channel 31) and became an affiliate of The WB. When Hearst-Argyle Television (which became Hearst Television in 2009) bought KCRA and its LMA with KQCA in 1999, the station dropped its "Q 58" branding in favor of using its call letters and channel number. Hearst-Argyle bought KQCA outright in 2000 after the Federal Communications Commission (FCC) began allowing duopolies, creating the first duopoly in the market in the process; the station adopted the "WB 58" branding in September 2004.
