The news: Despite leading competitors like Netflix in overall revenues, YouTube’s ad revenue growth is starting to slow, according to WARC Media and EMARKETER data.

• While YouTube generated over $60 billion in total global revenues last year—well ahead of Netflix’s $45.2 billion—YouTube’s ad revenue growth decelerated from 14.7% in 2024 to 11.7% in 2025, per WARC. WARC estimates that figure will drop to 7.9% by 2027. Netflix’s ad revenues, meanwhile, more than doubled in that period.
