John Shepard III was an American radio executive and merchant. Among his many achievements, he was one of the original board members of the National Association of Broadcasters, having been elected the group's first Vice President in 1923. Shepard co-founded a New England radio network, known as the Yankee Network, along with his brother Robert, in 1929-1930. Shepard was also an early proponent of Frequency Modulation or FM broadcasting: he established the first FM network, when he linked his station in Massachusetts with one in New Hampshire in 1940. He also was an early experimenter with home shopping, creating perhaps the first all-female radio station, WASN, in early 1927; the station broadcast some music, but mostly focused on shopping news and information about merchandise that listeners could purchase.
