KANM was founded in 1972 and is a recognized student organization at Texas A&M, one of the top ten largest universities in the U.S. with over 10,000 on-campus resident students. In the most recent month of SHOUTcast data (September 2008), KANM was one of the top college radio streams and among the top Internet streams in general, with nearly 500,000 stream connections. The station's web site claims that, at over 35 years old, it is likely the oldest surviving cable FM station in the country to have never transitioned to licensed over-the-air operation. Since the late 1990s, KANM has adopted other forms of broadcasting to augment the originally cable FM-only service, adding a Part 15 unlicensed AM broadcast and becoming an early adopter of Internet streaming audio in 1998. More recently, a campus cable television channel and downloads have also been added.
As of the fall semester of 2013, KANM now only broadcasts on their website and campus television channel 88.
