I didn't know they Cancelled "The Batman" animated series.

Anyone know just why they cancelled The Batman? I was looking for the season premiere and just to find out that they ended this animated series. Whats going on here. DCAU has not one show on TV right now. They even stop showing Superman:The Animated Series, Batman:The Animated Series, and i really don't know if they stopped showing Justice league Unlimited on Boom. The thing is, since I can remember, they have always had some kind of DCAU on TV and now I don't see any. Even Marvel got "The spatacular Spiderman" on the CW. So anyone know just what happen? I mean they cancelled it right when the JLA was being introduced in different episodes. What happen???
