We've seen unprecedented democratization of media over the last 30 years, primarily due to the internet. I'm personally not seeing a corresponding positive impact on cultural creativity. I see a lot of tweets and a lot of Etsy stores, and the audience for long novels (for example) is aging out.
You're not looking hard enough: indie video games, educational YouTube content being on par if not better than TV documentaries, countries generally not making great series, now being able to be seen by people anywhere, all sorts of great musicians and writers.
Like with everything one can see the positives or focus on the negatives. The Internet today has great, good, medium and bad content, just as before, what's different is the effort and excitement we used to have back then.
