>The Mézga Family on Holiday 1978
this is what i wanted to post. it's not even up to debate because it's a single continuous story arc from start to finish.
people here have such little knowledge of cartoons that they think a series from 2004 was the first to have continuity. and then it's a wonder why weebs can invade the board with claims of japanese cartoons doing everything sooner, and noone being able to prove otherwise.
