Protoculture Addicts was a Canadian-based North American anime and manga magazine published by Protoculture Inc., an Anime News Network company. The term "Protoculture Addicts" was also used by the Haydonites (an alien race that appeared in the Robotech: The Shadow Chronicles animated film) to refer to all the races that have been in contact with Protoculture.
Protoculture Addicts is the first large mainstream anime and manga magazine in North America. Its name derives from the popularity of the Robotech anime series, and its namesake, Protoculture. It started as a Robotech fanzine, became officially licensed as such, and then expanded to cover anime in general. Many of the series that it reviews and presents details thereof, including spoilers, are months in advance of legal release in the West.
