Not to be too much of an old man, but I do feel like the total digitalization of the world has sucked a lot of the scary mystery out of these things. Analog TV was spooky stuff! Local stations and public access led to some wild people getting on air. Depending on where you lived and how good your signals were, you could also pick up over the air pirate broadcasts or the ghostly partial images of the premium cable channels your parents couldn't afford. Was that a nipple you just saw... or a ghost?!
