A small disadvantage of modern technology

It is a wonderful advantage to be able to listen to collections of old radio shows. However, there is one slight disadvantage. When we hear several episodes of a particular program back-to-back, we notice things the original listeners probably would have overlooked because their hearings of the show were only once a week, or at some other space of time. If the writers got into a little bit of a rut, that becomes evident, as certain devices get overused. For example, we have two episodes of the Rocky Jordan show in which a character has lost his gun and says that it doesn't matter, because "there is strength enough in my arms" to take care of the hero. I suspect the original listeners would not have caught that repetition.
