The most popular subscriber-only Century articles

Having a subscriber-only paywall in front of most of our magazine content allows us to put the whole issue online and sell online-only subscriptions. Among other advantages, online-only subscriptions are cheaper—especially for folks who don't live in the States and would have to pay extra postage for print-magazine delivery.

This arrangement does, however, mean the articles behind the paywall generally get less traffic than the free ones. With this in mind, here's a separate top-12 list of just the paid content—i.e., the most popular articles of the year that were read online only by Century subscribers. Thanks, all of you, for supporting us. (If you don't subscribe, please consider it.)
