Since MoviePass slashed its monthly subscription costs last August from $50 to $9.95, its user base has exploded from roughly 20,000 to more than 2 million. In the process, it’s become the fastest-growing paid-entertainment subscription service in history, signing people at a greater clip than Netflix or Spotify. All that disruption in the movie theater business has created enemies and fueled skeptics, but whether MoviePass survives or dies, it has undeniably shaken up an industry that hasn’t changed much since the silent era.
