After Tribune acquired the station on April 26, 1999, the callsign was changed to KTWB-TV. In the meantime, Tribune placed KTWB in a trust-company for the short-term until the FCC formally approved television duopolies later that year, forming one with KCPQ. This logo is based on that of fellow WB station KWGN-TV in Denver.
This logo initially appeared on the FCC's online Public Inspection File for KZJO. On September 24, KZJO was rebranded as Fox 13+, becoming a brand extension of KCPQ. This branding is similar to those of several Fox-owned MyNetworkTV O&Os and independent station KICU-TV.
