Number of Stations: By the mid-20th century, Northern Arizona had only a handful of radio stations. KNAU was the first, but it wasn’t until later decades that more stations would join the airwaves.

Coverage: Initially, KNAU’s signal was limited to the immediate Flagstaff area, but expanded over time to reach much of Northern Arizona, providing a vital source of information and entertainment to more remote areas.

Programming: In its early days, KNAU focused significantly on educational content, reflecting its roots with Northern Arizona University. By the 1970s, the station had expanded its programming to include news, classical music, and community-oriented shows.

Impact and Evolution

The introduction of KNAU marked a significant milestone in Northern Arizona’s media history. It not only provided a platform for local voices, but also played a crucial role in emergency broadcasting, which was particularly important in an area prone to natural events like forest fires and snowstorms. The station’s commitment to public service has been a consistent theme, offering weather updates, emergency information, and community announcements.

Audience Growth: Over the years, the listenership of KNAU and subsequent stations in Northern Arizona has grown, paralleling the area’s population increase. From its inception, KNAU has seen a steady rise in audience, especially with the introduction of FM broadcasting, which provided clearer sound quality and broader coverage.

Technological Advances: The shift from AM to FM in the region allowed better sound quality and stereo broadcasting, significantly enhancing the listening experience and attracting a broader audience.
