The history of the VHS format is outlined in this interesting but somewhat monotonous documentary. I found I became somewhat bored with the continuous stream of interviews with VHS collectors and low-budget film-makers, but I loved the clips of obscure and forgotten films from the VHS heyday of the 70s and 80s. I'm going to have to find some of the films featured in this documentary.
I'm particularly intrigued by David "Rock" Nelson's monster movies. The Devil Ant, Conrad Brooks Vs. The Werewolf, and The Giant Horny Toad Monster are all available from him via mail order, but I'm a little wary about purchasing a $20 burned DV-R. I've spent more money on less, I suppose.
