“The first-ever disc jockey was actually the result of an experiment on live radio. A 16-year-old boy named Ray Newby played some records on air, catalyzing a movement that started in California and spread to the entire world. At this time, the term ‘disc jockey’ did not exist. It only appeared about 25 years later when the term was used by radio commentator Walter Winchell to describe music broadcasters on-air. This was also when the primary source of music were records, and not CDs or digital playlists.”
