YouTube Becomes TV-First, Shifting Ad Time and CPMs
Michael Beach argues that YouTube has transitioned from a mobile-first platform to a TV-first streaming service: it now captures 14% of total TV time and 28% of streaming TV time in the U.S., with streaming TV viewership on YouTube projected to be the largest share of its viewing time by 2027. YouTube streaming CPMs are substantially higher than mobile/desktop ($27 vs. $10), and YouTube generated approximately $40B in ad revenue in 2025 (about $10B in the U.S., $4B of which was CTV). Despite dominating viewing time, YouTube receives a smaller share of TV ad spend (12%), implying an underbuy relative to its audience share and signaling a potential reallocation of TV budgets toward YouTube.
A major platform (YouTube) shifting majority viewing to CTV with higher CPMs and significant audience share has material implications for TV budgets, media planning, and ad monetization across the streaming ecosystem.
