At 1:00 a.m. on September 10, 1995, WCIX and WTVJ swapped channel positions. The entire WCIX intellectual unit (CBS affiliation, programming, and staff) moved from channel 6 to channel 4, returning CBS programming to channel 4 after a six-year hiatus. WTVJ had been Miami's CBS affiliate from its sign-on in March 1949 until the 1989 switch to NBC. Along with the frequency change came a new set of call letters, WFOR-TV, changing the reference to the station's channel number from its original allocation to its new one. Due to the way the asset exchange deal was structured, the two stations were required to swap licenses in addition to the transmitting facilities. As a result, WFOR-TV legally operated under WTVJ's old license on channel 4 through the end of the analog broadcasting era; however, the studios of both WFOR-TV and WTVJ remained the same at the time of the swap (WTVJ has since moved to a new facility). The translators remained with the channel 6 facility.
