In 2016, The Intercept published some 1,800 stories. We covered everything from secrecy and corruption in politics to misuses of technology, attacks on civil liberties, environmental crimes, the police state, military adventurism, and the frequent failure of mainstream media to accurately report on and reflect the world around us. Here are 12 pieces that we recommend revisiting on the cusp of 2017. They don’t exactly make for light holiday reading — sorry about that — but we are deeming them must-reads because they each in their own way bring reality into sharper focus. We count on Intercept readers to derive a certain grim satisfaction from that. We’re grateful to all of you who read and shared our stories, and we hope you keep coming back. In a moment rife with uncertainties, at least one thing is clear: Adversarial journalism will be more important than ever in the years ahead. The SIDtoday Files

33 Thomas Street, one of the city’s weirdest and most iconic skyscrapers, has been a source of mystery for years. An investigation by The Intercept’s Ryan Gallagher and Henrik Moltke provides compelling evidence that the AT&T building is more than a mere nerve center for long-distance phone calls.
