Nickelodeon, according to the wonderfully reliable source that is Wiki, aired that 1993-1997.

I suspect it will be edited to a part, considering that's known in the UK as Hero Turtles, chopping the whole Ninja name out, but then keeping a lot of the fighting in it anyway.  Believe they later copied that in the States where the show originated to make it more family friendly, thus effectively making the original two or three seasons Early Instalment Weirdness.

Anyway wouldn't be the first time Nickelodeon buy something and then hack it to pieces so...

Never was my own cup of tea, but one of my siblings in their younger days was absolutely obsessed with it.  Wallpaper, clothes, probably videos as well...

TMNT have had more incarnations than Batman and Scooby-Doo!
