Toonami is a well of nostalgia for millennials whose introduction to anime included Dragon Ball Z, Gundam Wing, Sailor Moon and other classics.
Also, Toonami showed anime like Gundam Wing that was long-form and serialized, so viewers could really engage with some nuanced story lines and characters.
An entire generation’s fondness for anime can be traced back to one programming block on Cartoon Network called Toonami.
After a 4-year break, Toonami came back in 2012 and now airs Space Dandy, Attack on Titan and Kill la Kill.
