WCDC-TV (fictional)

WCDC-TV, virtual channel 19 (UHF digital channel 36), is a Telemundo owned-and-operated television station licensed to, United States and serving as well as 's  (––). The station is owned by the Telemundo Station Group subsidiary of NBCUniversal (itself a subsidiary of Comcast). WCDC shares studios with NBC affiliate and MyNetworkTV affiliate  (both owned by ) on North Pearl Street in Menands; its transmitter is located on, the highest peak in Massachusetts (making it the only full-power station serving the Albany–Schenectady–Troy market to not have its transmitter located on the ). Aside from the transmitter, WCDC-TV does not maintain any physical presence locally in Adams, making it the only Telemundo station licensed in to not be a part of the Telemundo Nueva Inglaterra station group.

Historically, WCDC-TV served as a semi-satellite of ABC owned-and-operated station WTEN, covering portions of western Massachusetts and southern Vermont that received a marginal to non-existent over-the-air signal from WTEN, although there was significant overlap between the two stations' contours otherwise. As a simulcast of WTEN, WCDC-TV was a straight simulcast; the only on-air references to the station were during Federal Communications Commission (FCC)-mandated hourly legal identifications. WCDC-TV was sold by ABC to in October 2016 and assumed the Telemundo affiliation for the Capital District from WSSP-TV (now a  affiliate) in December. WCDC-DT5 (mapped to 10.4) continues simulcasting WTEN as per a long-term agreement between ABC and NBCUniversal.

WTEN simulcast
WCDC began broadcasting on February 5, 1954 as WMGT (Mount Greylock Television) on UHF channel 74, the highest channel to ever be used by a full-power television station in U.S. history. WMGT began as a separate station affiliated with the DuMont network. The tower location on Mount Greylock (part of a state reserve) helped WMGT serve first as the market's secondary affiliate of DuMont and later as a major boost to WCDA. In December 1954, WMGT moved to channel 19 extending the station's range to the Capital District of New York State. In February 1956, it was forced off the air when a storm damaged its transmitter tower. Capital Cities bought the license and returned it to the air in 1957 under its final calls, WCDC. (The WMGT callsign now resides at an NBC-affiliated station in Macon, Georgia.) After Capital Cities returned WCDC to the air and until it was sold to ZGS, it served as a straight simulcast of WCDA/WTEN. Due to substantial snow and ice build-up, a tower collapse forced WCDC off the air again in March 1983. Most cable systems on the Vermont and Massachusetts sides of the market picked up WCDC's signal. Later on, WTEN's varying owners also leased some of WCDC's tower space to other entities, including the Massachusetts State Police and competitor WNYT for their area translator station.

WCDC's digital signal on UHF channel 36 signed on nearly eighteen months before WTEN's did in 2002. However, it did not upgrade to high definition until WTEN-DT signed-on. WCDC shut down its analog signal on channel 19 on June 12, 2009, following WTEN's lead.

Joining Telemundo
Citing declining over-the-air viewership, The Walt Disney Company announced a sale of WCDC in February 2017. On April 13, 2017, Disney announced it was selling WCDC to, with intentions to turn it into a Telemundo affiliate to serve the Capital District's Spanish-speaking population.

On April 16, 2017, ABC programming was interrupted so that WCDC could air what they called a "test broadcast" of Telemundo programming on 19.1. The sale was completed on May 4, 2017. The WTEN simulcast was moved to WCDC's second (later fifth) digital subchannel to maintain the simulcast for over-the-air viewers without clear reception of WTEN's signal.

On December 4, 2017, NBCUniversal's Telemundo Station Group announced its purchase of ZGS' television stations, including WCDC-TV. The sale was completed on February 1, 2018.

News operation
On February 18, 2018, WCDC-TV debuted locally produced 6 p.m. and 11 p.m. newscasts, hiring more than a dozen new staffers including anchor Dorothy Solanas and meteorologist Enrique Gracián. The newscasts are produced in the studios of and with technical support from NBC affiliate (channel 13), owned by. WCDC-TV uses separate on-air duratrans from WNYT and NBCUniversal's standard Telemundo O&O news graphics to differentiate the two stations' newscasts from each other.
