i don't know but i really wish it hadnt if you search for danny phantom fan websites you'll find people are still trying to get it back on the air and they actually have thousands supporting the theory they can bring it back!!!
And now I learn that they canceled the old episodes in nicktoons.I'm sad for that cuz I was gonna watch it on nicktoons for spring break so I saw the schedule online and there was no episodes... I really wanted to see it on spring break. :(
