WSB carried the syndicated version of "Family Feud" in the 1980-81 season (a purchase the station had made before switching to ABC and picking up the daytime version as well); "ET" debuted in the fall of 1981 and, as you noted, is still on Channel 2 at 7:30. In fact, in 33 years, Channel 2 has never changed its Monday-Friday 7-8 PM block of ABC News at 7 and "ET" at 7:30. (It is also, I believe, the only ABC affiliate in the Eastern time zone which still carries its network news at 7; to my knowledge, Montgomery, AL, is the only market that sees it at 6 (CT).)
That quote gave me an idea for this thread: Which Big 3 stations that you know of air their network evening newscasts at 7 ET / 6 CT? Are there any stations in the Mountain or Pacific time zones that do this?
