As Zacs has pointed out comprehensively in the first response on this thread - there are many and various factors that influence the culture and art that are made today, from what went before.
The simple fact is, audiences evolve as original audiences age, and younger people come through. What entertained us about Morecombe and Wise would leave the average under-twenty-five viewer cold, and wondering what all the fuss was about.
If we always had to enjoy what our parents liked, I would have sat through Max Miller and Jimmy Handley, not Monty Python and Fawlty Towers.
Times - and culture - move on, and amen to that.
