Postwar American Television
Zenith Phonevision
Zenith had experimented with pay television as early as 1931. By 1947 they had a working system and in 1951 they introduced Phonevision. After receiving FCC approval, they began a 90 day test run with 300 families from the Lakeview-Lincoln Park area in Chicago. More information on Phonevision can be found at the Chicago Television History site.
