Phonevision

A three-year commercial trial of Zenith's Phonevision[A] systems of
over-the-air subscription television has been in progress for the
Hartford, Connecticut area since June 29, 1962.

Authorized by the Federal Communications Commission, the trial has made
it possible, for the first time, for about 5000 American TV homes to
enjoy the convenience and economy of viewing top flight box-office
entertainment and other features broadcast to their home receivers.
Features at prices for the entire family no greater than a single
admission at the theatre, stadium or concert hall. The Hartford test has
already furnished factual information, rather than speculation,
concerning this brand new television service. On the basis of this
factual information, the F.C.C. has been requested to authorize
nationwide operation. If the F.C.C. is persuaded by the results of the
trial that subscription television is in the public interest and should
be authorized nationally, then every home could have its own "television
theatre" with the world's greatest and most costly entertainment offered
for an admission well below the cost of witnessing these same events
outside the home. With such premium-type programs added to entertainment
now available from sponsored television, the home viewer would be able
to obtain the ultimate of everything he wants to see on his own TV
screen.
