It varies a lot. Some newspapers might publish just a few dozen, while others could put out hundreds, depending on their size and focus.
Well, it's hard to give an exact number. Different newspapers have different publishing frequencies and coverage areas. Some might publish only a handful of major stories a day, while others flood their pages with a wide range of content, so it really ranges from a few to many dozens.
The number of stories published by newspapers each day can be quite different. Big national papers might have several hundred, but smaller local ones might have around 50 or so. It depends on factors like staff size, news sources, and the amount of advertising they have.
