Has anyone wondered why research papers had a 2 column format? I don't, but a few years ago I read Asimov's Nightfall short story through pdf on my phone and it was formatted with 2 columns.

Just now, I'm looking for short stories pdfs and found myself hating on most of them being formatted as prints in mind with only 1 column. The texts are so small you'd need to zoom in to read, but the lines are so long that you'd always need to scroll right and left, which is awful.
2 column format solved this problem, because the lines are shorter so it fits on phone screens and it doesn't ruin the looks when printed either.
More pdfs need to apply 2 column format, needs to be the standsrd notm istg.
