Looking at these Nintendo commercials from the '80s, I can't help but wonder whether advertising was just so much worse back then, or if kids are just more tolerant of bad jingles and the like.
Of course, I suppose it could be argued that the ads were really effective as I still remember both of them pretty clearly, which I guess is the point.
As an added bonus, I found this intro to the old Pac-Man Saturday morning cartoon. When I was little, I LOVED this cartoon (though I'm sure it's quite awful now in retrospect). When I'd get in trouble, my mother would ban me from watching it, but because it was on so early, I'd wake up to watch it before she work up.
