Menachem, many teshuvos have been written about reading news on Shabbos. Some say it’s necessary for safety purposes, but this would seem not to apply in our time.
Reading analysis of current events might… And this is a stretch… Be considered chochma, which is permitted to be read on Shabbos. But definitely the business articles are assur.
Thank you for mentioning captions; that’s something lots of people don’t know about – it’s very, very common in books and magazines that people read on Shabbos.
Im not clear if it applies to, say, pictures of gedolim in biographies. I think some allow it, but I don’t remember clearly.
