Relevant Radio is a 501(c)(3) non-profit organization headquartered in Lincolnshire, Illinois, with additional studios in Green Bay, Wisconsin.

The network was founded by a group of Catholic businessmen, including Bob Atwell and John Cavil (who purchased Kaukauna, Wisconsin-licensed station WJOK in 2000) and Mark Follett, the owner of Anchor Foods, an Appleton-based distributor of frozen appetizers known for its marketing of jalapeño poppers, which had been sold to Heinz and its proceeds being used to launch the network under the non-profit Starboard Media Foundation.

WJOK's calls, which formerly designated its sports radio format, now instead stood for the phrase Jesus, Our King.

"Morning Air", which the network describes as "a classic drive-time format that combines inspiration & entertainment" was the first program developed by Relevant Radio in 2003.

[1] The merger was completed on July 31, 2017, with all stations being licensed to Immaculate Heart Media, Inc., while Relevant Radio continued as the on-air branding.
