summary
YouTube handles 400 hours per minute of uploads and relies on machine learning and metadata to match users to videos because human curation is impossible at that scale. Open platform dynamics let creators build multi‑million person audiences and drive demand alongside algorithmic recommendations. Advertising shifts toward highly engaged audiences, mobile accounts for over 50% of viewership, and investment focuses on mobile-first formats like VR and 360 to capture rapidly growing video consumption.
