>Scenes require supporting media. In the age of print and broadcast, access to media was comparably limited. Consequently, the number of scenes was comparably limited.

If anything, it's the complete reverse. Scenes were more localized and had many different variations and unique cultures.

> The "something" that happened was the general public learning how the internet could be used to easily publish media for as many scenes as people could think of.

Which lead to a great consolidation, something we see in other areas as well. Regional cultures become less and less stark as national TV/news came about.

>It's now feasible for individuals to globally publish media regardless of how many other people are interested in it.

Which means the other scenes die out, and a predominant one appears. That's why you see flags and pronouns all across Twitter, but nothing much else. It's also why American culture is being exported globally, destroying unique cultures in its wake.
