Re: Full-Power Stations That've Always Been With the Same Network (O&O or Affiliate)
The NBC affiliates in the Kentucky edition of TV Guide:
WAVE, WLWT, and WLEX (even though WLEX carried
ABC and CBS shows in the '50s and '60s, and WAVE carried
some ABC shows before the arrival of WLKY, NBC has always
been their primary network); likewise WFIE Evansville, IN.
Roanoke/Lynchburg is the only market in Virginia which hasn't
played musical affiliations; WSLS (1952) started as an NBC primary;
WSET (1953) is ABC's oldest affiliate south of Washington (WLOS
is second); WDBJ (1955) has been with CBS from the beginning.
Greenville/Spartanburg/Asheville has also been stable: WFBC/WYFF
(NBC since 1953), WSPA (CBS since 1956), WLOS (ABC primary, then
ABC solely, since 1954).
Columbia, SC, likewise: WIS (NBC since 1953), WNOK/WLTX (CBS since
1953), WOLO (ABC since 1961). Charleston: WCSC (CBS since 1953).
Florence: WBTW (CBS primary since 1954, although a few NBC shows
in the '50s and several ABC ones as late as the late '70s). WPDE has
been ABC since sign-on in 1981; WMBF, NBC since sign-on in 2008.
Bristol/Kingsport/Johnson City: WCYB (NBC), WJHL (CBS), WKPT (ABC),
although WCYB and WJHL both carried some ABC shows until WKPT signed
on in 1969.
Nashville: WSM/WSMV (NBC since 1950), WLAC/WTVF (CBS since 1954).
WSIX/WNGE/WKRN started with CBS in 1953 but switched to ABC because
of WLAC's association with CBS dating back to radio days.
Washington, DC: WRC (NBC o&o from its beginnings in the '40s); WTOP/
WDVM/WUSA (CBS since 1949). WMAL/WJLA carried mainly CBS in '48 and
switched to ABC in '49. WTTG is tricky; for most of its life it was independent
(Metromedia), but if you consider DuMont and Fox to be a straight-line connection,
it might count, technically.
Charleston/Huntington: WSAZ (NBC since 1949)
Orlando: WDBO/WCPX/WKMG (CBS primary, then CBS solely, since 1953);
WESH picked up NBC in either '56 or '57, I'm not sure which; WLOF/WFTV
(ABC since 1958). In Tampa, WFLA has been with NBC since 1955.
