YouTube holds 28% of streaming TV viewing but only 12% of TV ad spend
A 28% share of streaming TV viewing time translates into just 12% of TV advertising dollars for YouTube, according to Cross Screen Media analysis of Nielsen and eMarketer data, a gap many analysts cite as evidence the platform remains underbought relative to its audience. YouTube's US ad revenue totaled roughly $10 billion in 2026, with about $4 billion of that tied specifically to TV-streamed-only viewing. Its CPM on streaming TV screens runs $27.43 by Needham and Associates estimates, well above the roughly $10 CPM it earns on mobile and desktop, though still short of the $40-45 CPM range Media Dynamics attributes to linear TV. Over 2021 to 2026, eMarketer data shows the streaming TV industry grew viewing 27% while YouTube grew 13.6%.
Deal terms benchmarked against click-and-scroll CPMs leave money on the table for buyers who already treat premium streaming as television, since YouTube's big-screen CPM of $27.43 sits far closer to linear TV pricing than to the platform's own $10 mobile and desktop rate. Agencies negotiating YouTube's place in TV budgets can point to Cross Screen Media's viewing-versus-spend gap as the case for shifting dollars toward its streamed inventory, and can request measurement built on currencies comparable to linear TV. A slate of higher-profile original series would strengthen that case, giving buyers the premium break inventory traditionalists say YouTube still lacks.
