Pretty much all major books are published as audiobooks as well. Even ones that have computer code written in them, which is not something that you’d ever expect to have read out loud.
It used to be that books would be “narrated for the blind” where not a lot of attention would be put into the audio. Nowadays, there tends to be a lot more effort put into them. I suppose that’s because they don’t need to be packaged as 12 to 20 cassette tapes or CDs any longer.
