Mobile game developers previously relied heavily on mobile operators for distribution, but operators only supported major studios and their subsidiaries. The introduction of app stores by Apple and Android opened up distribution to all developers by controlling accessibility, visibility, payment options, and certain app permissions. However, app markets have become more complex with operators, software vendors, and phone manufacturers launching their own stores, and third party app stores also emerging. Expanding into different distribution channels involves additional costs, requirements, and complexities for developers. The document discusses strategies for independent developers to build brands, utilize multiple distribution channels, and form partnerships to help address these challenges.
