'''Oregon Public Broadcasting''' ('''OPB''') is the primary [[public broadcasting|public media]] organization for the U.S. state of [[Oregon]] as well as southern [[Washington (state)|Washington]]. It provides news, information, and programming via television stations, dozens of [[VHF]] or [[UHF]] [[broadcast relay station#Broadcast translators|translators]], on more than 20 [[List of radio stations in Oregon|radio stations]], and via opb.org and other digital platforms. TV broadcasts include local and regional programming as well as programs from the Public Broadcasting Service ([[PBS]]) and [[American Public Television]] (APT), and radio programs from National Public Radio ([[NPR]]), [[American Public Media]] (APM), [[Public Radio Exchange]] (PRX), and the [[BBC World Service]], among other distributors. Its headquarters and television studios are located in [[Portland, Oregon]].

The part of southwestern Oregon not served by OPB is served by [[KLCC (FM)|KLCC]] radio, [[Jefferson Public Radio]], and [[Southern Oregon PBS]].

==History==
===20th century===
[[File:KOAC Building, date unknown (6218699912).jpg|thumb|190px|KOAC early studio and transmitter building near Oregon State University, {{circa|1941}}]]
OPB traces its roots back to January 23, 1923, when KFDJ signed on from the [[Oregon State University]] campus in [[Corvallis, Oregon|Corvallis]]. From 1923 to 1981, the Oregon State campus served as the radio and later TV base of operations for Oregon's public broadcasting. Charles B. Mitchel, a first-year speech professor at Oregon State, was instrumental in bringing Oregon's first public radio station to the state. OSU physics instructor Jacob Jordan is credited with building the station's first radio transmitter near campus in 1923.<ref>{{cite web |last1=Horton |first1=Kami |title=It all started as a lab experiment: A century ago, the broadcaster that became OPB was born |url=https://www.opb.org/article/2023/01/23/it-all-started-as-a-lab-experiment-a-century-ago-the-broadcaster-that-became-opb-was-born/ |website=opb.org |publisher=Oregon Public Broadcasting |access-date=31 March 2024}}</ref><ref>{{cite web |last1=Morris |first1=J.M. |title=The Remembered Years |url=https://ir.library.oregonstate.edu/concern/file_sets/td96k7454?locale=en |website=oregonstate.edu |publisher=Scholars Archive Admin at OSU |access-date=31 March 2024}}</ref> 

The radio station's call letters were changed to [[KOAC (AM)|KOAC]] on December 11, 1925. In 1932, KOAC became a service of the [[Oregon State Board of Higher Education]] General Extension Division.<ref name="Archive">[http://osulibrary.oregonstate.edu/archives/exhibits/koac/chrono.html KOAC timeline] {{webarchive|url=https://web.archive.org/web/20080906162836/http://osulibrary.oregonstate.edu/archives/exhibits/koac/chrono.html |date=September 6, 2008 }} from the [[Oregon State University]] website</ref>

During the mid-1950s, the university constructed KOAC's first TV studios inside [[Gill Coliseum]]. On October 7, 1957, the station began television broadcasting as KOAC-AM-TV. For nearly 60 years, faculty and students at Oregon State University broadcast news, information and entertainment programming across the state from the Corvallis studios.<ref>{{cite web |url=https://snaccooperative.org/view/35094608 |website=snaccooperative.org |title=KOAC (Radio station: Corvallis, Or.) |publisher=National Archives and Records Administration |access-date=July 20, 2023}}</ref> First known as Oregon Educational Broadcasting, the public network became the Oregon Educational and Public Broadcasting Service (OEPBS) in 1971.<ref>{{cite web |last1=Geddes |first1=Robert D |title=Report on Non-Commercial Television in Portland |url=https://pdxscholar.library.pdx.edu/cgi/viewcontent.cgi?article=1262&context=oscdl_cityclub |website=pdxscholar.library.pdx.edu |publisher=Portland City Club |access-date=10 March 2024}}</ref> 

KOAC won its first [[Peabody Award]] for [[List of Peabody Award winners (1940–1949)#1942|Outstanding Public Service by a Local Station]] in 1942 for ''Our Hidden Enemy, [[Venereal Disease]]''.<ref name="orlive100331">{{cite news| title= Oregon Public Broadcasting wins Peabody Award | author= Kristi Turnquist | url= http://www.oregonlive.com/movies/index.ssf/2010/03/oregon_public_broadcasting_win.html |date= March 31, 2010 | newspaper= [[The Oregonian]] | access-date= August 13, 2010}}</ref><ref>{{Cite web|url=http://www.peabodyawards.com/award-profile/our-hidden-enemy-venereal-disease|title="Our Hidden Enemy—Venereal Disease" for Outstanding Public Service by a Local Station|access-date=June 16, 2017}}</ref> KOAC won a second [[List of Peabody Award winners (1970–1979)#1972|Peabody Award]] in 1972 for ''Conversations with [[Will Shakespeare]] and Certain of His Friends''.<ref name="orlive100331"/>

[[File:KOAC TV Eugene studio.jpg|thumb|190px|KOAC-TV satilite studio at University of Oregon (Eugene), 1963]]

In the late 1950s, KOAC's broadcast signal was shared across the state by microwave transmitters and receivers. KOAC also added satellite studios for radio broadcasting in [[Eugene, Oregon|Eugene]], [[Monmouth, Oregon|Monmouth]], [[Salem, Oregon|Salem]], and Portland. In the 1960s, satellite TV studios were added in Portland and Eugene. The Portland satellite, KOAP-FM-TV, was located in a leased building at what is now 2828 SW Naito Parkway. KOAP started broadcasting on February 6, 1961. The Eugene satellite was located on the [[University of Oregon]] campus, in Villard Hall. Up until 1965, all programs from the KOAC satellites were live, due to a lack of video recording equipment. Both studios operated two [[RCA]] TK31 cameras for live broadcasts. 

On December 6, 1964, KTVR-TV began broadcasting in [[La Grande, Oregon|La Grande]]. The station started primarily as a [[commercial television]] station, affiliated with [[NBC]] and [[American Broadcasting Company|ABC]]. KTVR-TV operated as a semi-satellite of [[KTVB]] in [[Boise, Idaho]]. The La Grande studio was located at 1605 Adams Ave. and produced nightly newscasts and other local programming. However, by 1967, the La Grande studio and office were closed and KTVR became a full-fledged satellite of KTVB. KTVR was unique in the [[Pacific Time Zone]], because as a repeater of a [[Mountain Time Zone]] station, its "prime time" schedule was broadcast from 6 to 9 p.m. OEPBS bought KTVR on August 31, 1976, and converted it to PBS on February 1, 1977. At first, KTVR rebroadcast programming from two Washington stations—[[KWSU-TV]] in [[Pullman, Washington|Pullman]] and [[KSPS-TV]] in [[Spokane]]—until OEPBS completed a transmission link to La Grande. On September 1, 1977, OEPBS took KTVR off the air for transmitter repairs, due to increasing technical problems. KTVR returned to the air on January 1, 1978, carrying OEPBS programming for the first time.

{{see also|KVDO-TV}}
KOAB-TV in [[Bend, Oregon|Bend]] began broadcasting on February 24, 1970, as KVDO-TV, a commercial [[independent station]] licensed to Salem. Channel 3 struggled to compete with [[Portland, Oregon|Portland]]'s established independent, [[KPTV]] (channel 12), and in 1972, the station was purchased by Liberty Communications, then-owners of Eugene's ABC affiliate [[KEZI]] (channel 9). The intention was to make KVDO a full-power satellite of KEZI. During the sale, [[KATU]] (channel 2), Portland's ABC affiliate, objected over duplication of programming, and there were also objections to Liberty's common ownership of local cable systems and the television station. As a result, the [[Federal Communications Commission]] (FCC) allowed Liberty to buy KVDO-TV on the condition that it sell the station within three years.

The state government approved the purchase of KVDO-TV in 1975, with OEPBS taking control of the station on February 19, 1976. Nine days later, on February 28, a disgruntled viewer protesting KVDO's sale to OEPBS cut guy wires, toppling the channel 3 transmitter tower. On September 20, 1976, KVDO signed back on the air with a new tower; from then until March 31, 1981, the station broadcast an alternate program lineup to KOAP-TV and KOAC-TV, featuring time-shifted OEPBS programs, shows for the Spanish-speaking population in the [[Willamette Valley]], and several local productions in Salem. OEPBS consistently eyed moving the station elsewhere to reduce duplication, which became more acute when budget cuts prompted KVDO-TV to drop its separate programs in 1981. The network pursued and won approval from the FCC to move the channel 3 allocation and license to [[Bend, Oregon|Bend]], which had no PBS coverage. KVDO-TV ceased broadcasting in Salem on July 31, 1983; on December 22, channel 3 signed back on the air as KOAB. The call letters were modified to KOAB-TV when KOAB-FM signed on the air on January 23, 1986.

KEPB-TV in Eugene began operation on February 27, 1990, as Eugene's first public television station, bringing most of Eugene a clear signal for PBS programming for the first time ever. Although KOAC-TV had long claimed Eugene as part of its primary coverage area (Corvallis is part of the Eugene market), it only provided rimshot coverage to most of Eugene itself and was marginal at best in the southern portion of the city. Most of Eugene could only get a clear picture from KOAC-TV on cable.{{citation needed|date=December 2019}}

In 1981, OEPBS was spun off from the [[Oregon State Board of Higher Education|Oregon State System of Higher Education]] and became a separate state agency, Oregon Public Broadcasting. As part of the network overhaul, KOAP became the flagship of the OPB network and central operations were relocated from Corvallis to Portland.

In the early 2000s, OPB installed Oregon's first digital transmitter, taking a critical first step in the digital television transition.<ref name= "OPBHistory">{{cite web|url=http://www.opb.org/insideopb/#history |title=History of Oregon Public Broadcasting |publisher= OPB |access-date= July 31, 2014}}</ref>

===21st century===
For 2001 and 2002, the Oregon state government provided about 14 percent of OPB's operational budget; for 2003 and 2004, it was cut to 9 percent.<ref>{{cite news |title=Don't reduce funding for public broadcasting |newspaper=[[The Bulletin (Bend)|The Bulletin]] |location=[[Bend, Oregon]] |date=April 10, 2007 |url= http://www.bendbulletin.com/apps/pbcs.dll/article?AID=/20070410/NEWS0107/704100313&SearchID=7327774985 |access-date= August 13, 2010 }}</ref>

On December 4, 2007, OPB launched opbmusic, a 24-hour online radio channel spotlighting Pacific Northwest musicians.<ref>{{cite news| title= OPBmusic launches | author= Kristi Turnquist | url= http://www.oregonlive.com/music/index.ssf/2007/12/opbmusic_launches.html |date= December 11, 2007 | newspaper= [[The Oregonian]] | access-date= August 13, 2010}}</ref> As of December 11, 2020, OPB discontinued the opbmusic HD radio and online audio stream and integrated opbmusic multimedia content into its broader arts and culture reporting.<ref>{{cite web | title=Oregon Public Broadcasting’s Online Music Channel Will Cease Streaming Next Week | url=https://www.wweek.com/music/2020/12/04/oregon-public-broadcastings-online-music-channel-will-cease-streaming-next-week/ | date=December 4, 2020 | publisher=Willamette Week}}</ref>

In March 2009, the [[Corporation for Public Broadcasting]] chose OPB to manage the [[Pilot experiment|pilot version]] of American Archive, CPB's initiative to digitally preserve content created by public broadcasters.<ref>{{cite web| title= The Corporation for Public Broadcasting Selects Initiative Manager for American Archive Project | url= http://www.cpb.org/pressroom/release.php?prn=719 |date= March 26, 2009 | publisher= [[Corporation for Public Broadcasting]] | access-date= September 14, 2010}}</ref>

KOPB-TV and KEPB-TV are available on the Portland and Eugene [[DirecTV]] broadcast station lineups.

==Digital television==
OPB's first digital channel was OPB CREATE (an affiliate of the [[Create (TV network)|Create]] network), announced in January 2006; its availability was limited to certain Comcast digital cable customers and on Clear Creek Television in [[Oregon City]].<ref name="Jan06OPB">{{cite web| url=http://supportopb.org/insideopb/opbnews/opbarchives/television/#000919| title=Oregon Public Broadcasting Launches Its First Digital Multicast Channel| date=January 31, 2006| website=OPB.org| access-date=February 25, 2013}}{{dead link|date=March 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

In December 2008, in anticipation of the original February 18, 2009, deadline for [[Digital television transition in the United States|switching to all-digital broadcasting]], OPB announced the launch of three digital subchannels: OPB, which would air OPB programming with an "improved picture for viewers with traditional sets", OPB HD, airing programming in "high definition with the highest-quality picture and sound", and OPB Plus, which offered "more choices in viewing times and added programs in news, public affairs and lifestyle."<ref name="Dec10OPB">{{cite web| url=http://supportopb.org/insideopb/opbnews/opbarchives/television/#004805| title=OPB to Launch New Digital Television Channel Lineup| date=December 5, 2008| website=OPB.org| access-date=February 25, 2013}}{{dead link|date=March 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

OPB was one of the partners of [[The Oregon Channel]], a [[public affairs (broadcasting)|public affairs]] network that began with the 74th Oregon Legislative Assembly in 2007. Programming consisted of Oregon legislative sessions and other public affairs events. The Oregon Channel was discontinued in 2011.

All of OPB's digital channels are also available on cable providers [[Comcast Xfinity]], [[Charter Spectrum]] and [[Ziply Fiber]] (grandfathered TV subscribers), and three other providers serving specific regions and communities in Oregon: Clear Creek (a cooperative serving the [[Redland, Oregon|Redland area]] of [[Oregon City]]), [[BendBroadband]] (serving [[Central Oregon]]), and Crestview Cable Communications (serving [[Madras, Oregon|Madras]], [[Prineville]], and [[La Pine]]).<ref name="Dec10OPB"/>

On July 6, 2011, OPB combined OPB and OPB SD into one high-definition channel feed on the main channel of its digital stations. OPB Plus moved from the third digital subchannel to the second subchannel and OPB Radio moved from the fourth digital subchannel to the third subchannel.  

On January 26, 2023, OPB ended broadcasting of OPB Plus and replaced it with OPB World.

===Analog-to-digital conversion===
During 2009, OPB shut down the analog transmitters of the stations on a staggered basis. The station's digital channel allocations post-transition are as follows:<ref>[http://www.oregonlive.com/news/index.ssf/2009/02/portland_tv_stations_backtrack.html Portland TV stations backtrack, delay digital transition], a February 6, 2009, article from ''The Oregonian''</ref><ref>{{cite web |url=http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf |title=DTV Tentative Channel Designations for the First and Second Rounds |access-date=March 24, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20130829004251/http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf |archive-date=August 29, 2013 }}</ref>
* KOAC-TV shut down its analog signal, over [[VHF]] channel 7; the station's digital signal relocated from its pre-transition [[UHF]] channel 39 to VHF channel 7.
* KOPB-TV shut down its analog, signal, over VHF channel 10; the station's digital signal relocated from its pre-transition UHF channel 27 to VHF channel 10.
* KEPB-TV shut down its analog signal, over [[UHF]] channel 28; the station's digital signal remained on its pre-transition UHF channel 29, using [[virtual channel]] 28.
* KOAB-TV shut down its analog signal, over VHF channel 3; the station's digital signal remained on its pre-transition VHF channel 11, using virtual channel 3.
* KTVR shut down its analog signal, over VHF channel 13; the station's digital signal relocated from its pre-transition VHF channel 5 to channel 13.
