In some eps, movies and pro-novels, characters make reference to popular culture and history that they should be well past, particularly from the 20th Century. I think I finally have an in-universe solution, and forgive me if its already out there.
The war called WW3 wasn't all out, but it was ruinous. For a long while, much popular culture and historical info was lost. Historical research needs history to proceed from, and pop culture builds upon all that has gone before. In the process of surviving and rebuilding, people didn't have time for reflection or entertainment.
Sometime between Archer and Kirk, things finally settled in enough to allow for this. Then, a major sealed cache of documents and files were found--everything from Presidential and Prime Ministerial speeches to episodes of the Flintstones and I Claudius, Beatles, Bach and what have you. This began a slow reconnection with the past pop culture that persists into the 24th Century.
Ok, so this wasn't screaming to be solved. But is it a reasonable explanation?
