Later radio history increasingly involves matters of broadcasting.

With funding from the Ford Foundation (who also funded the National Educational Television and Radio Center (who later spun off its radio assets)), the network began broadcasting on six radio stations on April 3, 1961.
The Golden Age of Radio, also known as the old-time radio (OTR) era, was an era of radio in the United States where it was the dominant electronic home entertainment medium. It began with the birth of commercial radio broadcasting in the early 1920s and lasted through the 1950s, when television gradually superseded radio as the medium of choice ...
In 1958, The Standard School Broadcast received a Peabody Award for radio education, "in recognition of continuous expansion and development over a 30-year period. This outstanding music appreciation series for schools combines educational value with highest musicianship, expert production, and utilization of appropriate musical groups of all types, instrumental and vocal."
Before the discovery of electromagnetic waves and the development of radio communication, there were many wireless telegraph systems proposed and tested. [4] In April 1872 William Henry Ward received U.S. patent 126,356 for a wireless telegraphy system where he theorized that convection currents in the atmosphere could carry signals like a telegraph wire.

Chicago's program is regarded as the first large-scale experiment with "radio school". [2] Earlier, smaller-scale uses of radio for distance education had preceded this. In 1930, during a school closure in Marquette, Michigan, the station WBEO worked with the Daily Mining Journal to provide students with audible and textual instruction.
