WFSB did indeed use that campaign. I know they've been with CBS the entire time under their WFSB call letters, which date back to 1974 and CBS affiliation even further back. CBS was once on, of all channels, 18! Looking at that Univision affiliate today, you would never know it!
WVIT-TV channel 30 of New Britain/Hartford sets a record in this market. They are the only station in the market who has been with the same network since its inception in 1953.
Channel 8 of New Haven has been on since 1948, if you count their start as WNHC-TV channel 6. They cherry-picked CBS and Dumont at one time. Remember, channel 3 didn't sign on until 1957.
Channel 18 has a checkered past to say the least: CBS, pay-tv, indy, Gene Scott, informercials, off the air and now Spanish.
Channel 20 of Waterbury was WATR-TV and a secondary NBC affiliate until 1982. Channel 30 increased their signal making the secondary NBC affiliation unnecessary. They then became independent WTXX-TV. Today, they are our CW affiliate, WB before that. They picked up UPN about a year after the network's 1995 sign on. They would switch networks with channel 59 of New Haven who, at the end of 2000 going into 2001, went from WBNE-TV (WB) to WCTX-TV (UPN).
WTIC-TV (FOX) channel 61 of Hartford started out as an independent in 1984 and became a charter FOX affiliate in 1986-87 with Joan Rivers's talk show, etc.
