WOI (AM) is a non-commercial radio station based in Ames, Iowa, with a rich history dating back to the early 20th century. As one of the oldest radio stations in the United States, WOI has played a significant role in the development of public radio, evolving from experimental broadcasts to becoming a flagship station for Iowa Public Radio's News Network. This article delves into the historical journey of WOI (AM), highlighting key milestones and
its enduring legacy.
Early Beginnings
The origins of WOI (AM) can be traced back to 1911 when "Dad" Hoffman, a physics professor at Iowa State College, established a wireless telegraph station. By 1913, this station was known as experimental station 9YI, regularly sending and receiving weather reports via Morse code. These early transmissions laid the groundwork for WOI's future as a pioneer in radio broadcasting.
The first sound broadcast occurred on November 21, 1921, featuring an hour of concert music. This marked a significant transition from Morse code to voice broadcasts, paving the way for WOI to receive a full radio license from the Commerce Department in April 1922. The station's first regular broadcast took place on April 28, 1922, solidifying its place in radio history.
Expansion and Programming
In its early years, WOI focused on farm market reports and sporting events, catering to the interests of Iowa's agricultural community and sports enthusiasts. The station's programming evolved over time, with notable additions such as "The Music Shop" in 1925 and "The Book Club" in 1927, both of which became long-running favorites.
WOI's expansion continued with the launch of its FM sister station, WOI-FM, in 1949, and WOI-TV in 1950, marking its entry into television broadcasting. WOI-TV was the first commercial TV station owned by an educational institution, initially affiliated with all major networks before becoming solely an ABC affiliate in 1955.
Modern Era and NPR Affiliation
WOI-AM-FM became a charter member of National Public Radio (NPR) in 1971, aligning with NPR's mission to provide quality news programming. Today, WOI's programming includes NPR and locally produced talk shows, along with local news reports and BBC news updates.
In 2004, WOI became part of Iowa Public Radio, serving as the flagship for IPR's Operations and IT services. This merger consolidated the radio services of Iowa's state universities, enhancing WOI's reach and influence across the state.
WOI's historical journey reflects its adaptability and commitment to serving the community, maintaining its status as a cornerstone of public radio in Iowa.
