Teen Titans Go - New Series Promo 1
looks like some bad fan made flash or something.
anyway
have been listening to kevin smith's fatman on batman which has good info from dc animated people. some things i have gathered, most shows are either put on for 3 years (at most, 2 years/65 shows with extra orders in final year) and most of the ones that lasted more than 3 years were reformatted/renamed. fairly sure this has to do with voice/etc talent contracts.
one of the writers said in the beginning it was a good studio, but once they built the brand up, they really stop caring.
don't remember exactly when but believe it was before batman beyond came out, they were told, kids no longer watch shows where the hero isn't near their age and they needed to aim in that direction.
seems to explain the downward trend.
