Something I've always wondered. You've probably noticed that in some newspapers or books, the first few words of a chapter/story are bolded or capitalized, similar to initials. For example:
This image isn't from a real book, it's from an SE puzzle parodying a newspaper. It should convey my point though.
I've heard that this is a typesetting convention and it is not the writers who capitalize these words. However, what is the point? Is it recommended in publishing? Does it actually help readability, or is there some historical reason?
