I always thought that old TV shows that were done live were done so because there was no recording media. If that's true, then how do we have copies of them now? And if they did have recording equipment, why didn't they tape the shows and broadcast them like they do now? In the movie Contact they show a clip of the very first television broadcast (Hitler in Germany). Is the clip they show the real thing or is it a clip of something that was put on film? If it's the real deal, how was that recorded??
