Whatever else you might say about 2016, it was the greatest year yet for meme culture. Dozens of large and highly productive internet subcultures collided this year with mainstream cultural consumers: “Dat Boi,” the ubiquitous unicycling frog, freed himself from the labyrinths of Tumblr to ride across Facebook and Twitter; Hillary Clinton’s campaign felt compelled to explain “Pepe,” the (relatively) ancient 4chan meme adopted by the alt-right. Memes were no longer slightly embarrassing internet in-jokes but essential and omnipresent expressions of culture. For every day in 2016, Select All has picked one meme that either originated, broke through, or reached its height on that date, and done our best to explain it. (We’ll keep updating through the end of December.) The result is a collection of the best memes of 2016 — the funniest, weirdest, most outrageous, and most viral objects. It’s also, for better or for worse, a portrait of our collective unconscious: the story of our attention, and the things that managed to hold it, even briefly, throughout the year.
