The Progressive Broadcasting System (PBS) was an American radio network of the early 1950s. "[C]atering to smaller radio stations,"[1] the company had hoped to affiliate with around 1,000 radio stations in the United States which did not already have affiliation agreements with the "Big Four" national radio networks of those days: NBC, CBS, ABC, and Mutual, as well as Liberty, second in size to Mutual.
Time announced the company's formation on September 4, 1950. Broadcasts began November 26, 1950.[2]
