It was meant to be a FAMILY show for kids AND adults. Kids and adults could both feel connected to it. Unfortunately, when Stephen Hillenburg left it became just a kids' show...
No. It was intended to be a Nickelodeon show right from the start.
Not really. As far as I know, it has always been a children's show.
Yes it was.
People are saying that SpongeBob wasn't actually meant to be a kids show. People have been saying it was meant to be an adult show like South Park, or Family Guy. It is kind of believable to me though, because Sandy CHEEKS, lives in BIKINI BOTTOM, and SpongBob and Patrick have like the biggest bromance ever, so what's your opinion?
