Seems like some manufacturers will claim their product is magical hoping buyers will fall for the hype. Case in point is Rocky Teller's Magic-Glass Arrows. From Archery magazine, April 1953.
He had a TV show in Duluth, MN in the 1960s on station WDSM, had a weekly segment on WDSM radio, owned a sporting goods store and was a camping outfitter.
In answer to your question...yes, the radio and TV station had the same call signs. Now only the radio station is still operating.
