YouTube lived off venture capital, search sponsorships, and content hosting. Venture capital is long dried up. Search sponsorships are just advertisements but clogging your searches. Content hosting isn’t really needed anymore since every large media company has their own streaming platform. Lot has changed since 2006.
YouTube has already been helpful to a degree. Sometimes I’ll open their AI summarize and it will give all the details along with timestamps. There are videos where I saw the summary and passed on watching because the video was mostly filler material.
