Naruto was one of Shonen Jump's big 3 series that kept them going for a long time. The manga managed to last from 1999 all the way to 2017, which is a full 18 years. The anime for Naruto, combining Naruto and Naruto: Shippuden managed to last from 2007 all the way to 2017, which is a full decade of episodes that I'll remember fondly.
