It's from Nickelodeon it seems so I guess you need to have the channel first and then watch it and watch it when they did it....
I mean where I am from the private cable tv wasn't as common so it was easier for people to see most of the stuff as all was free over the air tv, as long as you had a tv and antenna that's it.
On America it seems like it would be easier I guess for people not see certain things if they didn't have cable or their didn't have certain channel or similar.
I wish I could claim I wasn't from the US because its embarrassing to live here right now, but I am. Never watched a single episode of blues clues, it was popular when I was in high school.
