I vaguely remember Twilight Zone going to an hour when I was a little kid. I believe the Alfred Hitchcock half hour show might have been made an hour long for a season too. I believe it was just to cash on more commercials. The shows were better at the shorter length.
Note: This season of The Twilight Zone was used as a midseason replacement for the show that had replaced it on the 1962 fall schedule. To fill the timeslot, episodes were lengthened to one hour and moved to Thursday nights.
