Dragonball Z On Cartoon Network/Toonami

Hey, I dont know about the USA, But in London Dragonball Z Episodes Used to show on Toonami about 6 Years ago, I was wondering, How comes it hasnt shown since?

I also remember reading on some blogs and forums that they have removed it from air circulation, I think this show should definatly be brough back.

I think even Dragonball and Maybe GT used to show too, But I cant remember fully.

What do you think?
