More and more people have come to realize that anime is a legitimate form of entertainment, and those same people have also realized that not all anime is intended for children. That being said, shonen is the most popular type of anime because it is geared towards young adults, but many of those series cover fairly mature subject matter. Hunter X Hunter debuted as a manga in 1998 and has had two anime adaptations so far, with the 2011 version covering more of the story.
