This document discusses the different potential platforms for distributing VR content, including app stores, downloads, and browsers. It notes both advantages and disadvantages of each approach. App stores provide discovery, user reviews, and monetization capabilities but are limited by their interfaces and policies. Downloads require more commitment from users and aren't well-suited for casual experiences. Browsers have no downloads but monetization is less clear and performance lags behind native apps. The document concludes developers should consider cross-platform solutions or choosing a specific platform to maximize their chances of success in the emerging VR distribution landscape.
