Damon learned the other day that before the Teenage Mutant Ninja Turtles could be launched in eight countries in Europe, the censorship board/laws made them change their name to Teenage Mutant Hero Turtles. Obviously, they found a negative connation/association with ninjas they didn't want children exposed to. According to Wikipedia, consequently, everything related to the Turtles had to be renamed before being released in these nations (comic books, video games, toys, etc.) The lyrics were also changed, such as changing "Splinter taught them to be ninja teens" to the "Splinter taught them to be fighting teens."
This continued until 2003.
This begs the question: What about the naked lady lingerie advertisements in the newspapers? Or the use of the word "fuck" on prime time TV?
I guess in this corner of the world, that's far more conservative than a cartoon turtle welding a toy knife.
