Why Did sailor moon stop going on cartoon network?

Because only the 1st 4 seasons were ever released as a US dub.

I think I saw her on Robot Chicken.

because cartoon network only had the licenceing to show so many of the eps.
I remember when it was on fox kids and it only ever showed 1 and half seasons repeadildy -_-

I think after the last episode they aired on cartoon network they did not have anymore DUBBED episodes.

Because the show on Toonami had expired since May 3, 2001.

Because she was shot and killed. Not really, it just got cancelled over time. Now that Cartoon Network has terminated Toonami almost a year ago, there's no chance that they will ever show it. Cartoon Network has sure made a lot of unnecessary changes lately.

bcoz of the ecchi

loss of popularity
