Oregon Public Broadcasting
non-profit organization in the USA
Oregon Public Broadcasting (OPB) is the primary public media organization for most of the U.S. state of Oregon, as well as southern Washington. It provides news, information, and programming via television stations, dozens of VHF or UHF translators, on more than 20 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 on South Macadam Avenue in Portland, Oregon.
The part of southwestern Oregon not served by OPB, including Medford and Klamath Falls, is served by Jefferson Public Radio, and Southern Oregon PBS.
History
20th century
OPB traces its roots back to January 23, 1923, when KFDJ signed on from the campus of Oregon Agricultural College (now Oregon State University) in Corvallis. From 1923 to 1981, the OAC/Oregon State campus served as the base of operations for educational broadcasting in Oregon. Charles B. Mitchel, a first-year speech professor at OAC, was instrumental in bringing Oregon's first public radio station to the state. physics instructor Jacob Jordan is credited with building the station's first radio transmitter near campus in 1923. It was one of several AM stations signed on by land-grant colleges in the early days of radio.
The radio station's call letters were changed to KOAC on December 11, 1925.
This brief starts where responsible research should: with the source description of “Oregon Public Broadcasting” as non-profit organization in the USA. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as non-profit organization in the USA. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q7101297. 1 of 2 selected statements include explicit references; 2 carry qualifiers and 1 use preferred rank. The first chronological checks are 1923, 1981 and 1925.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
