If you look at anime DVD sales for the West it's almost all for older series. New shows don't blip very high, unlike Japan.
Where the anime studios would be making the bulk of the western money is through Crunchyroll and other licensees. Crunchyroll is estimated to have
750,000 users as of Dec 2015. Putting that together with
other data, Crunchyroll's total user base has been estimated:
Nov 2011: 70,000 subscribers
Sept 2012: 110,000 subscribers (+4000 / month)
March 2013: 200,000 subscribers (+15000 / month)
Nov 2014: 400,000 subscribers (+10000 / month)
Dec 2015: 750,000 subscribers (+25000 / month)
When Crunchyroll had 400,000 subscribers the revenue was estimated at 300 million yen per month. That's almost doubled since Nov 2014. So we're looking at CR having a yearly turnover of around $US 72 million. They'll probably crack $100 million in annual turnover within a year at the current rate of growth. That's no small potatoes. CR is a mainstream media player now. And a bigger user base only means better things: it reduces their per-customer cost so they can keep subscriptions reasonable, while allowing them to get a wider variety of content and host better servers. Part of the rise is probably due to people getting better connections as time goes on and streaming becoming more viable, plus the rising age and income of the typical western anime viewer (anime viewers age, just like video game players do), meaning more people prefer to pay rather than pirate.
Meanwhile I found an interesting tidbit. The
Love Live School Idol phone game has
14 million registered users in Japan. That's over 10% of the
entire nation of Japan, and represents almost 1/3 of the 50 million smartphone users in the country. Those are some pretty huge market numbers.
