Loads of them. And not just Wikipedia articles, longwinded articles from every other source under the sun. Usually ones on sites with minimal CSS and Javascript, because they use less data than the alternatives.
Admittedly a lot of people would probably just stick to browsing Facebook or Twitter most of the time, but even then, they'll look up tons of small facts and trivia pieces through Google whenever they don't know something too. In the olden days, that wasn't possible. Even less people looked up stuff they were curious about, since it meant either having to go home and online (before phones) or bringing out the encyclopedia (before computers in general).
