. "The Rural Radio Network (RRN) was an interconnected group of six commercial FM radio stations spread across upstate New York and operated from Ithaca, NY -- the first all-radio, no-wireline network in the world. It began operation in 1948 as an innovative broadcast service to the agricultural community, but competition from television\u2014and a lack of affordable, well-performing FM receivers\u2014caused the founders' original business plan to fail."@en . . .
