Overview
Citynet Network Marketing and Productions, Inc. (CNMPI) is a Philippine media company associated with GMA Network, Inc. It functions as a licensee and operating subsidiary for television services, most visibly the Metro Manila station DWDB-TV. Although the company is less publicly prominent than the GMA Network brand, its corporate role has been connected to several important stages in the development of GMA’s secondary television services. CNMPI’s best-known broadcasting project began with the launch of Citynet Television 27 on August 27, 1995. The service was conceived as an independent-style UHF television outlet that could carry imported programs, particularly material from the United States, while GMA’s principal channel concentrated on locally produced programming. The station also carried selected Philippine productions, including Citynet Television News and Citycourt, a dramatic anthology based on notable legal cases in Philippine history. CNMPI’s news and public-affairs work was linked to GMA News and Public Affairs and included cooperation with regional business-news organizations such as CNBC Asia and Asia Business News. The independent-programming model was difficult to sustain. Competition from ABS-CBN-associated Studio 23 and the high costs of running a separate schedule led GMA to alter the station’s format. In 1999, the service briefly adopted the EMC, or Entertainment Music Channel, identity before becoming Channel V Philippines under an arrangement with STAR TV. Channel V Philippines officially began on December 19, 1999, making DWDB-TV a locally operated music-television outlet. The arrangement ended on July 25, 2001, after ownership changes involving PLDT created a conflict with the company’s existing relationship with MTV Philippines and amid intensifying competition. After a period off the air, the station returned in 2004 as a relay of GMA-7 Manila. From November 2005, it also served as a repeater for QTV, GMA’s secondary television service created through an agreement with ZOE Broadcasting Network. The analog UHF service was later vacated as GMA prepared digital-television tests. Beginning in February 2013, GMA used the channel 27 frequency for digital test transmissions based on the Japanese ISDB-T standard. CNMPI again became strategically important in 2019 when GMA ended its long-running blocktime arrangement with ZOE Broadcasting Network for channel 11. To preserve the availability of GMA’s news service in Metro Manila, DWDB-TV’s channel 27 frequency was returned to analog broadcasting and became the originating Manila outlet for GMA News TV on June 4, 2019. GMA’s digital transmissions were moved to UHF channel 15, the frequency assigned by the National Telecommunications Commission for its primary digital feed. On February 22, 2021, the service carried by the station was relaunched as GTV. The new network broadened the format beyond the predominantly news-oriented GMA News TV identity by combining news, entertainment, and sports programming. DWDB-TV’s feed is now distributed through GMA’s digital television infrastructure, including a digital subchannel associated with DZBB-TV. The station and its sister services also moved to 16:9 widescreen presentation in February 2023. CNMPI therefore represents an operating and licensing vehicle behind a succession of GMA-affiliated television concepts rather than a consumer-facing product brand with a broad standalone portfolio.
History
CNMPI’s documented public history is closely tied to the GMA Network television station DWDB-TV. The station launched as Citynet Television 27 on August 27, 1995. GMA designed it as an independent-style UHF service whose imported programming would complement, rather than duplicate, the locally focused schedule of the main GMA channel. Its limited original programming included Citynet Television News and Citycourt, while the station also experimented with internationally sourced content. The original model did not remain viable. High operating costs and competition from Studio 23 encouraged GMA to replace the independent schedule with a music-oriented format. The station temporarily became EMC in 1999 and then, following a deal with STAR TV, launched Channel V Philippines on December 19 of that year. The music channel ended on July 25, 2001. The ending was associated with PLDT’s investment in GMA and the resulting conflict with PLDT-related MTV Philippines interests, as well as the competitive environment. Programming returned to the frequency in 2004 through a relay of GMA-7 Manila. In November 2005, DWDB-TV became a repeater for QTV, a secondary GMA service operated through a relationship with ZOE Broadcasting Network. The arrangement helped extend reception into parts of southern Metro Manila. The analog frequency was later vacated as GMA prepared digital-television trials. GMA began ISDB-T digital tests using channel 27 in February 2013. These transmissions carried GMA and GMA News TV services. In 2019, the station’s role changed again when GMA and ZOE ended their channel 11 blocktime agreement. GMA repurposed channel 27 for the analog Manila feed of GMA News TV, which resumed transmission on June 4, 2019. At the same time, GMA’s primary digital transmission moved to UHF channel 15. The channel was relaunched as GTV on February 22, 2021. GTV adopted a broader news, entertainment, and sports format while retaining substantial news content. The station’s digital feed is distributed through GMA’s digital television system and, according to the cited station history, is carried through a DZBB-TV digital subchannel. In February 2023, the feed moved to 16:9 widescreen presentation. These developments illustrate CNMPI’s role as a corporate vehicle supporting successive GMA broadcast services, rather than as an independently marketed entertainment brand.
