I actually thing that millenials (i.e. the parents of 2025 children) read more than any other generation. Just not books.

Until recently, the internet was mostly text, we didn't have the bandwidth for anything else. And it meant reading. Text messengers took the place of phone calls, even more reading. Text was also how video games told stories, more reading. And finally, subtitles, they keep growing in popularity, so even when you are watching videos, you are reading.

GenX was all about TV, boomers spent more time outside and talking, and if you get far enough back, people didn't even know how to read. I think GenZ still read a lot, but now, audiovisual content is more prevalent on the internet than it was before. Also, audiobooks gained in popularity.

Maybe we should make define what "reading" is. Is it actual reading, as in textual communication, or is it consuming books, but in this case, do audiobooks count?

If you only count reading paper books, then sure, people read less, but that's because there are so many alternatives nowadays. And maybe some attention deficit.
