Here’s an image spot for WTIC-TV (channel 61), a Connecticut television station that affiliated with FOX in 1986. Prior to that it was independent. The spot is from October of 1992 and was likely part of the station’s 1992-1993 image campaign. Although it features FOX network programming like The Simpsons and Married… with Children, it is most definitely promoting the station, not the network. The WTIC News at 10 is briefly seen, as are syndicated programs like Star Trek: The Next Generation (first-run) and Full House (off-network).
The spot starts abruptly but I don’t know if it was supposed to run for 45 seconds or a full minute. If the latter, a good chunk of the spot is missing.
