Dial Communications Inc.

Owned by John Sewall, who was a professional broadcaster in and around the twin cities of Minneapolis and St. Paul, Minnesota. His voice was heard coast-to-coast over WCCO radio, and was a show host for the largest night time radio audience in the nation. His production company Dial Communications, set up in 1969, was responsible for producing sound tracks for many companies during the time when audio visual slide presentations were the state of the art media.
