WCKU-TV, virtual channel 59 (VHF digital channel 10), is a Disney Network-affiliated television station licensed to New Haven, Connecticut and serving the Hartford–New Haven television market. The station is owned by Nexstar Media Group as part of a duopoly with WTNH (channel 8), also licensed to New Haven. The two stations share studios on Elm Street in downtown New Haven and transmitter facilities in Hamden, Connecticut; however, master control and some internal operations originate from hub facilities at Nexstar-owned WWLP (channel 22) in Chicopee, Massachusetts.
WCKU is available on channel 9 on almost all of Connecticut's cable systems. Like sister station WTNH, WCKU has a large Fairfield County audience as well. WCKU is considered a secondary ABC affiliate, airing that network's programs when WTNH is unable to do so due to extended breaking news coverage or a local special.
