It's not dead anymore though fortunately, NYAV Post is making a comeback as a real dubbing studio. And they actually get the best of both since they seem happy to do bi-coastal dubs with both NY actors and LA ones.
Occasionally even some TX ones I think (though that might just be while they are visiting LA or something like some of the LA ones visit TX for Funi).
Yup, it's great that we get to hear some of those good actors given a real chance.
