Make that about five years earlier.

>>There were no directional FM or TV stations.<<

Wrong.  There certainly were...and are...directional FM's and TV's.  However, since there are no tuning networks to be adjusted or drift out of tolerance (the patterns are determined solely by the spacing of the elements with respect to the tower and each other, and placement of parasitic elements in the near-field of the antenna), they were never subject to the old First-Phone operator requirements, unless they were above a certain power level.
