The rise of anime
We need to look at Japan in order to get a sense of the scope of the voice acting industry:The anime industry set a record in 2016 with revenues of 2.01 trillion, or $17.7 billion, according to the Association of Japanese Animations.
TV, film, internet distribution, and merchandise all contribute to this total, which is driven by overseas sales, which account for the majority of revenue.
Even outside of Japan, actors will have more opportunities as a result of their international renown.
