A very pleasurable thing is old TV on DVD. The picture quality is so good, and the best thing, NO COMMERCIALS.
Columbo often appeared under the umbrella program, the NBC Mystery Movie. NBC made me go to school dead tired many times as a kid. Almost as fun as watching the program was the thrill and fear of getting caught staying up so late by my parents. This may be part of the desire to see those good old programs once again.
Hmmmm, what to get?
