Rod Serling recited the most famous intro in TV history 50 years ago today:

“There is a fifth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man’s fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call ‘The Twilight Zone.'”

To celebrate “The Twilight Zone’s” 50th birthday, Syfy, which regularly broadcasts the show, is airing a 15-episode marathon, starting at 8 a.m. (EDT). Anniversary observances are also taking place this weekend in Binghamton, N.Y., where Serling grew up and went to high school; at Ithaca College, where Serling taught from 1967 until his death in 1975; and at Antioch College in Yellow Springs, Ohio, where Serling was a student and taught.
