Completely anecdotally:

I am 46yo. And I was in a reading slump for most of my fourties. I used to be an avid reader until I became a father and my 3 children began taking up more of my time. And I got a shorter attention span too.

I signed up for TT because my eldest child wanted an account and I wanted to see what he was sharing and seeing. He abandoned his account quite quickly, but I found fantasy booktok. And the Tiktokers' youthful enthusiasm was a big part of what got me out of my years-long reading slump.

I doubt if this happens often enough to be industry changing, but it does happen, even for someone very much outside the Tiktok demographic.

As an aside: where it does seem to have an influence is more people in the Dutch language zone reading books in English. I have been reading in English since I was 12 and at the time many people thought that was crazy. But nowadays every bookshop has a wall full of English Fantasy en YA books.
