DYVC-TV

DYVC-TV, channel 4 (digital UHF channel 18), is the Visayas flagship station of the VGC television network licensed to Mandaue City, and serves the Central Visayas super-region through two external signals (see below). It is owned by the network's VGC Television Stations division as part of a duopoly with independent station DYCH-TV (channel 12). It is also sister to radio stations DYVC (846) and DYVC-FM (102.3). DYVC-TV's studios are located at Peacock Drive in Mandaue City. Transmitter facilities are also located there, which is shared with DYCH-TV (along with the digital spectrum).

While Cebu stations are generally considered the Visayas flagships, and channel 4 was considered one, it did not become an owned-and-operated station until mid-2021 when Greater East Media merged its television cluster with VGC.

Early years
The Radio Corporation of America, having already been a key source of technology for the establishment of Manila's television stations, wanted to settle its own businesses in Cebu, having already owned radio station DYNB (693, now defunct) since its inception in 1935 as KZCR.

DYNB-TV signed on the air on December 7, 1953, a few weeks after DYCJ-TV (channel 30, now a Central O&O) of VGC's now-defunct newspaper The Cebu Journal (later revived as an online news website).

While technically, channel 4 was not affiliated with any network at the time, it later acknowledged its early years as an NBS station. Because of RCA's significant funding on the NBS network, including the fact that the company's US broadcaster NBC TV supplied most imports on the network, meant RCA was able to broadcast the entire network lineup of the then-duopoly of DZVM-TV and DZNB-TV in the Metropolitan area. However, despite the similar call letters, NB in DYNB-TV stood for NBC (which managed the Peacock Broadcasting subsidiary that owned the station until 2021).

NBS later left channel 4 in favor of purchasing an upstart television station, DYCU-TV (channel 5), from Chronicle-Tribune Broadcasting, a joint venture between two American newspapers, the San Francisco Chronicle and the Chicago Tribune that managed most of the deYoung family's assets in the Philippines. (The Chronicle later acquired the Tribune 's stake in the joint venture, and the remaining broadcast assets became sister stations with channel 4 in 2021; see below). After three years as a secondary affiliation, channel 4 became an exclusive ENetwork affiliate until 1959 when locally-based Sentinel Corporation (later the Cordoba Company), which published the Cebu Sentinel, launched DYQC-TV (channel 10) and took ENetwork with it, owing to DYQC radio's affiliation/programming agreement with DZPH radio.
