You've carved out a huge swath for yourself in the IP TV cartoon arena.
Excellent choice. For many reasons. Kids like cartoons, and so do adults. So many avenues to take with this one. Also you may not be aware of this, but cartoons play better on smaller devices (i.e mobile phones) then do regular shows. It seems that it's easier on the eyes (and brain) to follow cartoons on screens that small. So right now as we speak, legions of cartoon content is being created "for the day".
Not to worry on this being a plural. I'll be honest the singular is better, but is still a premium, keyword TV domain.
Best of Luck!
