literal books have been written on the subject
So 30 year old books that talk about press during wartime being propagandist in some cases, with bias in others and heavily politiced in most, sure.
Do you have a source for stating AP spreads propagand routinely nowadays?
These 30 year old books describe the mechanics of western media, which last I checked, haven’t substantially changed today. If anything, propaganda has ramped up as a result of a proxy war with Russia.
another comment in this very thread has the sources regarding AP specifically https://lemmy.ml/post/18538110/12620401
