Some predicted that established publishers with big budgets, experienced developers, and huge brand names would quickly dominate the mobile markets.But a new analysis by mobile analytics firm Flurry completely demolishes that prediction, showing that established publishers only control about one third of the games being played on mobile platforms.

Big console and PC game publishers have certainly tried to muscle their way in, but iOS and Android have given rise to new publishers that dominate the platform.
