In the late '60s and early '70s, KNOE-8 in Monroe, La. carried ABC's evening cast at 5 PM, followed by Cronkite at 530. At the time, they were CBS primary and ABC secondary .... nearby KTVE-10 in El Dorado, Ark. was NBC/ABC.
This continued until around '72 or so, when KTVE became an ABC primary (eventually they'd return to NBC, where they are today).
Birmingham, Ala.: When WBRC-6 switched from CBS to ABC in 1961, WAPI-13 (now WVTM) ran CBS and NBC back-to-back when both were still 15 minutes. When both expanded, 13 dropped CBS and aired just NBC. (side note: WBRC would drop ABC's evening cast in 1967 when they went to 30 minutes, and did a 15' local "world news" followed by their regular "Alabama Newsreel" -- they didn't carry ABC Evening News again until August 1972).
