When I was a young child, back in the day of VHS tapes, my brothers and I would watch a particular pair of movies over and over as our sources of entertainment. One of which was Batman (1966) and the other was Star Trek IV: A Voyage Home (1986). Of course, neither of these were related other than in our hearts, but both of these were taped off the television for our repeated viewing. One of the things that was special about recording things off the TV is the archiving process of commercials. It is like a time capsule of a particular culture. Nevertheless, for kids sitting on the floor or the couch, watching the same movies repeatedly, you not only memorize the movies, but you also memorize the advertisements.
Now, this is just a simple framing of the story.
