NBC (ended 1973)
I just found out that Universal Studios will be releasing the complete third season of Night Gallery on DVD!! The set will also include the previously "lost"segment 'Witches' Feast' and the rarely seen 'Die Now, Pay Later' in its original format.
I just got mine in the mail today. I'm watching my way through season one now. I grew up on The Twilight Zone, but Night Gallery re-runs were much rarer, so I'm far less familiar with the series.
