Covid definitely shook things up, but clubs didn't do well even before covid, while festivals were thriving. Now, it is a bit hard to tell as 2024 was just the second "normal" year, and it can take many years to grow a successful event.

It seems like now, we are indeed seeing less festivals, but the remaining ones are becoming bigger and more expensive. So, maybe less festivals but higher budgets.

Weren't there several mass casualties at clubs? I wonder if those had an effect overall. Anecdotally, I remember after several of the movie theatre shootings in the US, my immediate peer group self included decided it just wasn't worth it. Only in the last year or so have I started coming back to theatres.

I live in France and I saw many night clubs close for reasons I think are unrelated to security. I remembrer an entire street with nothing but night clubs, some of them quite famous, they closed down one after the other, the last one was in 2017 I think. I lived next to the beach for most of my teens, we had two night clubs, none of them remain, the next town has one that still remains but another one that closed in the early 2000s not to open again, a major electronic music came in its place, incidentally cancelled last year for financial fraud raisons. Where I live today, I saw one night club close, I think in 2019 (before covid) but I didn't see one open. In fact, I don't remember seeing a night club open since the early 2000s. Plenty of bars, but not night clubs.

These are anecdotal evidence, but that's a lot of anecdotes.

In none of these case I saw a particular event motivating this, I guess it was just not profitable. Also worth noting that most night clubs that are still open tend to get terrible reviews on Google (less than 3/5 on average). It is kind of a meme to complain about nightclubs you go to, especially if you get denied entry, but still, not very encouraging.

No, not in the UK, not enough to be noticeable at least. We have sensible gun laws and so don't generally have mass casualty incidents, and don't panic when we do. (See e.g. the London Bridge van incident and pint guy).
