# List of former NBC television affiliates

The National Broadcasting Company (NBC) is an American broadcast television network that originated as a radio network in November 1926, and expanded into television in April 1939. Throughout its history, the network has had many owned-and-operated and affiliated stations.
This article is a table listing of former NBC stations, arranged alphabetically by state, and based on the station's city of license as well as its Designated Market Area; it is also accompanied by footnotes regarding the present network affiliation of the former NBC-affiliated station (if the station remains operational) and the current NBC affiliates in each of the listed markets, as well as any other notes including the reasons behind each station's disaffiliation from the network. There are links to and articles on each of the stations, describing their histories, local programming, and technical information, such as broadcast frequencies.
The station's advertised channel number follows the call letters. In most cases, this is their virtual channel (PSIP) number, which may match the channel allocation that the station originally broadcast on during its prior affiliation with the network.

## Former affiliate stations

Stations are listed in alphabetical order by city of license.
| City of license/Market | Station/Channel | Years of affiliation | Current affiliation | Current NBC affiliate | Notes |
| Altoona-Johnstown-State College, Pennsylvania | WFBG-TV 10 (now WTAJ-TV) | 1953–1955 (secondary) | CBS | WJAC-TV 6 | Secondary affiliation, with CBS as its primary affiliation. Disaffiliated from NBC in 1955. (At the time, Altoona/State College was a separate market from Johnstown, who already had an NBC affiliate (WJAC-TV), and WFBG-TV/WTAJ-TV had long claimed the Johnstown market as part of its coverage area.) |
| Ames-Des Moines, Iowa | WOI-TV 5 (now WOI-DT) | 1950–1954 (secondary) | ABC | WHO-DT 13 | Secondary affiliation, with CBS as its primary affiliation. Lost NBC affiliation upon the sign-on of WHO-TV due to WHO radio's long-time affiliation with the NBC Radio Network. |
| Fort Dodge-Des Moines, Iowa | KQTV/KVFD-TV 21/50 | 1953–1977 | Defunct | WHO-DT 13 | Served as the NBC affiliate for the Fort Dodge area. Ceased operations in 1977 due to a tornado causing damage to KVFD-TV's studio and transmitter, and the next year's death of station owner Edward J. Breen. |
| Des Moines, Iowa | KDSM-TV 17 | 1984–1987 (secondary) | Fox | WHO-DT 13 | Cleared NBC programs not cleared by the network's existing affiliate WHO-TV. Disaffiliated from NBC in 1987. |
| Anchorage, Alaska | KTVA 11 | 1965–1970 (secondary) | Rewind TV | KTUU-TV 2 (previously with NBC as KFIA/KENI-TV from 1953 to 1970 (secondary from 1967 to 1970)) | Secondary affiliation, with CBS as its primary affiliation. Shared with ABC affiliate KENI-TV. Lost NBC affiliation when independent station KHAR-TV joined the network in 1970. |
| Anchorage, Alaska | KHAR-TV 13 (now KYUR) | 1970–1971 | ABC | KTUU-TV 2 (previously with NBC as KFIA/KENI-TV from 1953 to 1970 (secondary from 1967 to 1970)) | Swapped affiliations with ABC affiliate KENI-TV in October 1971, reuniting NBC with its original Anchorage affiliate (KFIA/KENI-TV was a joint primary of NBC and ABC from 1953 to 1967, and a secondary affiliate (with ABC as its primary affiliation) from 1967 until KHAR-TV took the NBC affiliation in 1970). |
| Anderson-Greenville-Spartanburg, South Carolina-Asheville, North Carolina | WAIM-TV/WAXA 40 (now WMYA-TV) | 1979–1989 (secondary) | MyNetworkTV | WYFF 4 | Secondary affiliation (WAIM-TV/WAXA was an independent station before becoming a charter Fox affiliate in 1986); cleared NBC programming not cleared by the network's existing affiliate WYFF. Disaffiliated from NBC in 1989 when WAXA left the air due to financial and management problems (it resumed operations in 1991 as a satellite of ABC affiliate and future virtual sister WLOS-TV, thus precluding any further broadcasts of NBC programming). |
| Asheville, North Carolina-Greenville-Spartanburg, South Carolina | WASV-TV 62 (now WYCW) | 1998–2000 (secondary) | The CW | WYFF 4 | Secondary affiliation, with The WB as its primary affiliation before it joined UPN in 1999. Cleared NBC Sports coverage of sporting events not cleared by NBC's existing affiliate WYFF due to other programming (including breaking news, severe weather coverage and/or telethons). |
| Atlanta, Georgia | WSB-TV 2 | 1948–1980 | ABC | WXIA-TV 11 | Swapped affiliations with ABC affiliate WXIA-TV due to ABC looking for a stronger affiliate in Atlanta (at the time, ABC had better ratings than NBC, which was in last place among the three major networks). The deal reunited ABC with its original Atlanta affiliate, since WSB-TV carried a secondary affiliation from 1949 until WXIA-TV signed on (as WLTV) in 1951. |
| Atlanta, Georgia | WVEU 69 (now WUPA) | 1985–1986, 1989–1994 (both secondary) | Independent | WXIA-TV 11 | Secondary affiliation (WVEU was an independent station); cleared NBC programming not cleared by the network's existing affiliate WXIA-TV. Disaffiliated from NBC in 1986 when the station began airing programs from the Home Shopping Network, and again in 1994 due to the impending sign-on of UPN. The station had also recently acquired programming from WGNX, which had just become a CBS affiliate. |
| Rome-Atlanta, Georgia | WAWA-TV/WTLK-TV 14 (now WPXA-TV) | 1988–1994 (secondary) | Ion Television (O&O) | WXIA-TV 11 | Secondary affiliation (WAWA-TV/WTLK-TV was an independent station); cleared NBC programming not cleared by the network's existing affiliate WXIA-TV. Disaffiliated from NBC in 1994 when WTLK-TV became a country music video/infomercial-based station. |
| Augusta, Georgia | WJBF 6 | 1953–1974 (secondary from 1967) | ABC | WAGT-CD 26 | Relegated its NBC affiliation to secondary status (with ABC as its primary affiliation) on September 1, 1967, citing no significant out-of-market competition, and that NBC's affiliate in Columbia, South Carolina, WIS-TV, provided grade B coverage to the South Carolina portion of the Augusta market, whilst no full-time ABC affiliate had such coverage into the area. From December 1968 to 1970, WATU-TV served as a full-time NBC affiliate; however, NBC allowed WJBF and CBS affiliate WRDW-TV to "cherry-pick" its strongest programming because, in addition to its weak signal, television sets in the area were not capable of receiving UHF channels. Disaffiliated from NBC entirely when WATU-TV returned to the air in 1974. |
| Augusta, Georgia | WRDW-TV 12 | 1967–1974 (secondary) | CBS | WAGT-CD 26 | Secondary affiliation, with CBS as its primary affiliation; shared with ABC affiliate WJBF. From December 1968 to 1970, WATU-TV served as a full-time NBC affiliate; however, NBC allowed WRDW-TV and WJBF to "cherry-pick" its strongest programming because, in addition to its weak signal, television sets in the area were not capable of receiving UHF channels. Lost NBC affiliation when WATU-TV returned to the air in 1974. |
| Augusta, Georgia | WATU-TV/WAGT 26 | 1968–1970, 1974–2017 | Defunct | WAGT-CD 26 | Initially left the air in 1970, unable to compete with WRDW-TV and WJBF because, in addition to its weak signal, television sets in the area were not capable of receiving UHF channels, but returned to the air in 1974. Left the air for good in 2017 when the station's spectrum was sold in the FCC's broadcast incentive auction. WAGT's NBC affiliation was then moved to sister station and YouToo America affiliate WAGT-CD. |
| Austin, Texas | KTBC 7 | 1952–1966 (secondary) | Fox (O&O) | KXAN-TV 36 | Secondary affiliation, with CBS as its primary affiliation. Disaffiliated from NBC in 1966 in favor of KHFI-TV, who signed on in February 1965 but could not join NBC for over 1 1/2 years due to contractual obligations. |
| Austin, Texas | K49CY/KBVO-LP/KBVO-CA 49 (now KBVO-CD) | 1989–1995 | MyNetworkTV (satellite of KBVO) | KXAN-TV 36 | Translator station of NBC's existing affiliate KXAN-TV; initially left both its simulcast and NBC to become a charter affiliate of UPN in 1995. |
| Llano-Austin, Texas | KLNO/KXAM-TV 14 (now KBVO) | 1991–2009 | MyNetworkTV | KXAN-TV 36 | Semi-satellite of KXAN-TV; used to improve that station's signal in portions of the Hill Country. Broke from its KXAN-TV simulcast and disaffiliated from NBC in 2009 to become a full-time MyNetworkTV affiliate, taking that affiliation from CW affiliate KNVA (which KXAN-TV's then-owners Media General were operating under a LMA) who had previously aired MyNetworkTV programming on a secondary basis. |
| Bakersfield, California | KERO-TV 10/23 | 1953–1984 | ABC | KGET-TV 17 | Swapped affiliations with CBS affiliate KPWR-TV in 1984. KPWR-TV then changed its call letters to the current KGET-TV to reflect the new affiliation. |
| Baltimore, Maryland | WJZ-TV 13 | 1966, 1969–1971 (secondary) | CBS (O&O) | WBAL-TV 11 (previously with NBC from 1948 to 1981) | Simulcasted NBC Sports coverage of World Series in which the Baltimore Orioles participated due to Major League Baseball regulations at the time allowing participating teams' flagship stations to simulcast World Series games (WJZ-TV was the Orioles' television flagship at the time). |

W. Scripps Company's group affiliation agreement with that network, while WJZ-TV joined CBS through a group affiliation agreement between CBS and Westinghouse Broadcasting (and would eventually become a CBS O&O), and NBC rejoined their original Baltimore affiliate WBAL-TV (which disaffiliated from NBC in 1981). |
| Bangor, Maine | WABI-TV 5 | 1953–1959 | CBS | WLBZ 2 | Swapped affiliations with CBS affiliate WLBZ-TV due to WLBZ-TV's association with WCSH-TV, the NBC affiliate in Portland. (WABI-TV had aired CBS programming as a secondary affiliation until WLBZ-TV signed on as WTWO-TV in 1955.) |
| Baton Rouge, Louisiana | WAFB-TV 9 (now WAFB) | 1953–1955 (secondary) | CBS | WVLA 33 | Secondary affiliation, with CBS as its primary affiliation. Lost NBC affiliation upon the sign-on of WBRZ-TV. |
| Baton Rouge, Louisiana | WBRZ-TV 2 | 1955–1977 | ABC | WVLA 33 | Swapped affiliations with ABC affiliate WRBT due to ABC looking for a stronger affiliate in Baton Rouge (at the time, ABC was the highest-rated television network in the country). |
| Bay City-Flint-Saginaw, Michigan | WNEM-TV 5 | 1954–1995 | CBS | WEYI 25 | Swapped affiliations with CBS affiliate WEYI through a two-station affiliation agreement with WNEM-TV's owners, the Meredith Corporation, tied to the renewal of the latter network's affiliation with Kansas City affiliate KCTV. |
| Beaumont-Port Arthur, Texas | KBMT 31 (now on channel 12) | 1954–1956 | ABC | KBMT-DT2 12.2 | Ceased operations in 1956 due to the inability of television sets to tune to UHF channels without an UHF adapter, and returned to the air in 1961 on channel 12 as a full-time ABC affiliate (by then, KPAC-TV had signed on as a full-time NBC affiliate). |

Initially lost its NBC affiliation upon the sign-on of KGHL-TV, but regained it when the station, by then called KULR-TV, switched its primary affiliation to ABC in 1968. Left NBC for good in 1982 when independent station KOUS-TV became a full-time affiliate of the network, although the station has dropped some network programming two years earlier. |

Between then and April 1996 when WICZ's full-time Fox affiliation began, the station heavily preempted NBC programming in favor of Fox Kids programming. Elmira-based NBC affiliate WETM-TV subsequently launched a cable-only version of the station to serve the Binghamton area under a LMA with Time Warner Cable. This programming would eventually move to W08DL in 1997. |
| Birmingham-Tuscaloosa-Anniston, Alabama | WBRC 4/6 | 1949–1954 | Fox (O&O from 1995 to 2008) | WVTM-TV 13 (O&O from 1996 to 2006) | Swapped affiliations with CBS affiliate WABT due to WBRC's acquisition by Storer Broadcasting, a company with strong ties to CBS. |

Left the air in April 2018 due to both the sale of WMFP's spectrum in the FCC's broadcast incentive auction (with its main channel continuing operations under a channel-sharing agreement with Evine affiliate WWDP) and NBC's acquisition of WYCN-CD (which also sold its spectrum and entered into a channel-sharing agreement with PBS member station WGBX-TV, allowing full-market coverage of WBTS-LD). |

| Casper, Wyoming | KTWO-TV 2 | 1957–2003 (secondary from 1957 to 1984) | ABC | KCWY 13 | Disaffiliated from NBC due to an affiliation agreement between the network and Pax TV affiliate KCWY. KTWO-TV then announced it would become an ABC affiliate in June 2004 (in the interim becoming an independent station with a secondary Pax TV affiliation), but outgoing ABC affiliate KFNB agreed to end its affiliation early, and KTWO-TV switched in March. KFNB subsequently became a Fox affiliate KLWY and made sister station K26ES (previously a translator of Cheyenne-based Fox affiliate KLWY) a full-time UPN affiliate. |
| Riverton-Casper, Wyoming | KWRB-TV/KTNW 10 (now KFNE) | 1957–1984 | Fox (satellite of KLWY, Cheyenne) | KCWY 13 | Shared affiliation with CBS affiliate KTWO-TV. Disaffiliated from NBC in 1984 and became a full-time ABC affiliate. |

From December 1953 to March 1955, WAYS-TV (later WQMC-TV) served as a full-time NBC affiliate; however NBC allowed WBTV to "cherry-pick" its strongest programming because, in addition to its weak signal, television sets were not required to have UHF tuning capabilities at the time. Lost NBC affiliation upon the sign-on of WSOC-TV. |
| Charlotte, North Carolina | WAYS-TV/WQMC-TV 36 | 1953–1955 | Defunct | WCNC-TV 36 | Ceased operations in March 1955.

Channel 36 allocation is now occupied by NBC's current Charlotte affiliate, WCNC-TV. |
| Charlotte, North Carolina | WSOC-TV 9 | 1957–1978 | ABC | WCNC-TV 36 | Disaffiliated from NBC due to ABC looking for a stronger affiliate in Charlotte (at the time, ABC was the highest-rated television network in the country).

The station signed off in 2008, before moving to New Jersey in 2014 following a protracted review of PMCM TV, LLC's application to the Federal Communications Commission to relocate the station through a legal loophole that allows any VHF television station automatic permission to move to a state that does not have any commercial VHF stations of their own.

WAAY-TV regained a secondary NBC affiliation in the early 1980s to clear NBC programming not cleared by WAFF, most notably Late Night with David Letterman and/or Friday Night Videos which WAFF preempted in favor of evangelist Jimmy Swaggart's daily program.

| Durham-Raleigh-Fayetteville, North Carolina | WRDU-TV/WPTF-TV/WRDC 28 | 1968–1995 | MyNetworkTV | WRAL-TV 5 (previously with NBC from 1956 to 1968 (primary from 1956 to 1962)) | Disaffiliated from NBC and became a full-time UPN affiliate (which WRDC had already been airing in late-night) due to dissatisfaction by NBC over WRDC's persistent low ratings. |

Disaffiliated from NBC for good in 1996 due to an affiliation agreement between Fox and KEVN/KIVV-TV's incoming owners, Blackstar LLC. NBC programming was unavailable over-the-air in the Rapid City market until KNBN signed on in 2000. |

NBC demanded that Young run the station under the conventions of an NBC O&O as a condition of renewing its affiliation; Young refused these demands, along with the affiliation renewal.

Ceased operations in April 1955 due to the inability of television sets to receive UHF signals without the use of a converter, which resulted in low viewership. After a failed attempt to return to the air as a satellite of ABC O&O KGO-TV, the channel 36 license was returned to the FCC in 1956.

| Shreveport, Louisiana-Texarkana, Texas | KTBS-TV 3 | 1955–1960 | ABC | KTAL-TV 6 | Disaffiliated from NBC when CBS disaffiliated from KCMC-TV, citing that the signal of its Shreveport affiliate KSLA decently covered Texarkana, Texas, KCMC-TV's city of license. Fearing that it would have to make its secondary ABC affiliation its primary (since ABC was in the last place among the three major networks at the time), KCMC-TV's owners successfully persuaded the FCC to collapse the Texarkana television market into the Shreveport market. KCMC-TV subsequently elevated its secondary NBC affiliation to primary status, while KTBS elevated its secondary ABC affiliation. |

(KDLT-TV had previously been part of a regional network-affiliated primarily with NBC (but also broadcasting ABC on a secondary basis) with KSFY-TV, but since the stations were separately owned, the FCC ruled in 1969 that their "network" was illegal and the stations should instead compete.) |
| South Bend-Elkhart, Indiana | WSBT-TV 22 | 1952–1954 (secondary) | CBS | WNDU-TV 16 | Secondary affiliation, with CBS as its primary affiliation. Lost NBC affiliation upon the sign-on of WSJV. |

In the 1950s, as KMO-TV, it lost the NBC affiliation upon the sign-on of KOMO-TV (due to KOMO radio's affiliation with the NBC Radio Network) and became an independent station.

| Terre Haute, Indiana | WTHI-TV 10 | 1954–1965 (secondary) | CBS | WTWO 2 | Secondary affiliation, with CBS as its primary affiliation. Lost NBC affiliation upon the sign-on of WTWO. |
