Akira Toriyama's Dragon Ball Z originally aired from '89 to '96, and nearly 25 years later, it's still just as popular. Dragon Ball Z is frequently viewed as a signature shonen series that helped define the '90s and pushed the animated medium forward in important ways. Dragon Ball Z has several anime peers that were also incredibly popular during their initial runs, only to later fall into obscurity.
