Having wasted...er...watched incalculable hours of the idiot box in my lifetime I recall there were ghosts a’plenty on my family television. In the early days the ghosts I remember came from poor reception, and required adjusting the rabbit ears antenna until the ghosts on the screen went away. That isn’t good enough for horror comics, which often used the dead as returning to life, in this case in a ghostly form, to get back at those who put him in his grave.
