references 5 external links history edit as an independent station edit wdca s logo under superior tube ownership used throughout the 1970s . wdca tv signed on as an independent station on april 20 1966 ; it was originally owned by the capitol broadcasting corporation . channel 20 was washington s third independent station nearly 20 years younger than its future sister station wttg which had been founded as a dumont affiliate and after wook the nation s first african american oriented television station . veteran washington broadcaster milton grant who previously worked at wttg was president of capitol broadcasting and also served as wdca s founding general manager . grant would sell channel 20 three years later in 1969 to the superior tube company although he would stay on as wdca s general manager for the next decade . 2 in 1979 superior tube sold wdca to cincinnati based taft broadcasting but only after an earlier proposed sale to the chicago based tribune company fell through . 3 4 5 in the 1970s and 1980s wdca s best known personality was dick dyszel who played bozo the clown horror movie host count gore de vol and kids show host captain 20 and also served as the station s main announcer . the station was also home to petey greene s washington an emmy award winning show featuring the witicisms and observations of ralph petey greene civil rights activist and native washingtonian . under taft s stewardship channel 20 became very profitable . as taft upgraded the programming much of which was distributed by new sister company worldvision enterprises especially hanna barbera cartoons wdca gained higher ratings but still trailed wttg overall . for most of the 1980s and early 1990s wdca was the flagship broadcaster of the washington bullets and washington capitals . it was also the washington d.c. home of the baltimore orioles . channel 20 also became a regional superstation appearing on cable television systems up and down the east coast . at its height it was available on nearly every cable provider in maryland and virginia and was carried as far south as charlotte north carolina and as far north as harrisburg pennsylvania . as early as 1987 when it was displaced on charlotte area cable providers by upstart independent station wjzy now a sister station to wdca under fox ownership wdca began losing most of its out of market cable audience as more independent stations signed on in its former cable footprint . however it is still available on several cable providers in maryland and virginia . in february 1987 taft sold wdca and its other independent and fox affiliated stations to the norfolk virginia based tvx broadcast group . at the same time the station dropped its longtime branding of tv20 and became known as dc20 . the taft purchase created a debt load for tvx and the sale of their smaller market stations did not fully reduce the debt . in mid 1989 tvx sold a minority interest in the company to paramount pictures . two years later in 1991 paramount bought tvx s remaining shares and became full owner of the stations which were renamed as the paramount stations group and as a result wdca changed its branding to paramount 20 like its houston sister station ktxh . viacom purchased the group as part of its acquisition of paramount pictures in 1993 . as a upn station edit in 1994 chris craft industries and its broadcasting subsidiary united television partnered with viacom s newly acquired subsidiary paramount pictures to form the united paramount network . wdca became the network s washington area station when the network debuted on january 16 1995 . at the network s launch wdca was an affiliate of upn as chris craft had wholly owned the network at the time ; the following year viacom whose relationship to upn was initially in the form of a programming partnership bought a 50 % ownership stake in upn from chris craft ; this effectively turned channel 20 into a upn owned and operated station through viacom s part ownership viacom later bought chris craft s remaining 50 % interest in upn in 2000 . on october 29 2001 viacom traded wdca to the news corporation s fox television stations unit along with ktxh in houston in exchange for kbhk tv in san francisco resulting in the creation of the first television duopoly in the washington d.c. market . fox merged the two stations operations with wdca moving from its longtime studios in bethesda maryland into wttg s facilities on wisconsin avenue nw in washington s friendship heights neighborhood . wttg was itself once related to paramount pictures it was originally an o & o of the dumont television network which paramount had owned in part . as a mynetworktv station edit logo as dca 20 following the cw announcement january to may 2006 . wdca s first my 20 logo used from may to june 2006 . on january 24 2006 cbs corporation and time warner announced that upn and the wb television network would be shut down to be replaced by a new network that would feature some of the higher rated programs from both networks called the cw television network . 6 7 wb affiliate wbdc channel 50 now wdcw was announced as washington s cw station due to its owner tribune broadcasting having signed a 10 year affiliation agreement for 16 of the company s 19 wb stations . the day after the announcement of the cw s formation january 25 2006 fox removed all network references from the on air branding of its upn affiliates and stopped promoting upn programs altogether . wdca accordingly changed its branding from upn 20 to dca 20 and altered its logo to replace upn s logo with the dca lettering . the formation of mynetworktv with wdca and the other fox owned upn stations as the nuclei was announced on february 22 2006 less than one month later . 8 with the impending switch to mynetworktv channel 20 s on air branding was changed to my 20 beginning on may 5 2006 . despite mynetworktv s announcement that its launch date would be september 5 2006 upn continued to broadcast on stations across the country until september 15 2006 . while some upn affiliates that switched to mynetworktv aired the final two weeks of upn programming outside its regular primetime period wdca and the rest of the network s fox owned affiliates dropped upn s programming entirely on august 31 2006 . wdca will often take the responsibility of airing regular fox programming from sister station wttg such as in january 2016 when the washington d.c. area was crippled by a blizzard wdca aired regular fox programming so wttg could devote their entire schedule to long form news and weather coverage . digital television edit digital channels edit the station s digital channel is multiplexed channel video aspect psip short name

officially launched on august 13 11 beginning in october of 2012 . it did so until around august 2015 when a change in ownership in mundofox saw fox s interest in the network end and its renaming to mundomax . three months later the 20.3 subchannel became home to the classic tv network heroes & icons . analog to digital conversion edit on june 12 2009 wdca terminated its analog signal on uhf channel 20 as part of the federally mandated transition from analog to digital television . 12 the station s digital signal remained on its pre transition uhf channel 35 . through the use of psip digital television receivers display wdca s virtual channel as 20 . wdca s digital signal had been very weak due to a problem with washington d.c. in constructing a new transmitter tower . however around august 10 2006 it was operating at full power and the signal became receivable in the suburbs . mobile dtv edit in july 2009 washington d.c. became a test market for mobile dtv and wdca was one of the participating stations . 13 like all of the dc area mobile dtv broadcasters wdca commenced full time atsc m h broadcasting on february 27 2011 . wdca also has a mobile dtv feed of sister station wttg displaying as subchannel 5.1 labelled wttg fox5 and a feed of wdca on 35.2 with two encrypted video feeds of fox news channel on 5.3 and the fox business network on 5.4 broadcasting at 5.5 mbit s. this is tied with wfdc dt for the highest bit rate of any d.c. area television station s mobile feed . 14 15 newscasts edit in july 1995 wdca experimented with a half hour nightly 10 00 p.m. newscast called upn 20 news at 10 to compete with wttg s longer running primetime newscast . the newscast was produced by regional cable news channel newschannel 8 . the newscast was discontinued in the summer of 1996 . in october 2006 while wttg aired fox sports coverage of the 2006 major league baseball postseason the first half hour of that station s 10 p.m. newscast was broadcast by wdca under the title fox 5 news at ten special edition ; this also occurred in 2007 with the wdca broadcast of the program being titled my 20 news at 10 . references edit digital signal sources . the
