Among Us

Innersloth released Among Us in 2018. Nobody played it. Two years later, Twitch streamers discovered it during lockdown and it hit 500 million monthly active users — the most viral game in history. Three developers built it; at peak, it was generating $86 million per month on mobile alone. The social deduction gameplay ("who's the impostor?") entered everyday language: "sus" became a generational slang term. AOC played it on Twitch to drive voter registration and hit 435,000 concurrent viewers. From dead-on-arrival to cultural phenomenon in 24 months.
