Horace Dediu, on Apple’s having paid $10 billion to App Store developers in 2014:
Put another way, in 2014 iOS app developers earned more than
Hollywood did from box office in the US.
Although the totals for Domestic (US) Box Office are not the
complete Hollywood revenues picture, Apple’s App Store billings is
not the complete App revenue picture either. The Apps economy
includes Android and ads and service businesses and custom
development. Including all revenues, apps are still likely to be
bigger than Hollywood.
