WTVJ ended its 40-year affiliation with CBS on January 1, 1989, and became the third station in Miami to have carried programming from NBC. CBS moved the rest of its programs over to WCIX, while WSVN became the new Fox affiliate for South Florida; most of WCIX's syndicated programs, such as most of its cartoons and sitcoms—with exceptions such as "I Love Lucy", "Family Ties", "" and a few others—went to WDZL (channel 39, now CW affiliate WSFL-TV). In a bit of irony, WTVJ also continued to preempt NBC's noon offerings in favor of carrying a local newscast. That timeslot would be given back to the network's affiliates in 1991. Shortly after the switch, the station debuted an image campaign based on the Bobby McFerrin song "Don't Worry, Be Happy", that lasted until 1993.
