KJAM-FM long served the Madison, South Dakota area as a companion to KJAM-AM, expanding the station’s reach on the FM dial and bringing enhanced sound quality to listeners across eastern South Dakota and western Minnesota. Over the years, KJAM-FM delivered a variety of music formats, evolving alongside audience preferences while maintaining a strong connection to the local community.

As part of a new era under Christensen Broadcasting, the station underwent a transformation designed to better position it for today’s listeners. This transition included not only a refreshed programming approach, but also a complete rebrand.

In 2026, KJAM-FM officially became KMZM, marking a bold step forward in both identity and sound. The new call letters reflect a modern vision for the station, focused on delivering a distinct listening experience while complementing the company’s growing regional network.

Today, KMZM represents the next chapter in a legacy of local broadcasting – combining forward-thinking programming with the same commitment to the communities it serves. While the name has changed, the mission remains the same: to provide engaging, relevant radio for listeners across the region.
