Overview
- Barb’s four‑screen reach data shows YouTube at 51.9 million UK viewers in December versus about 50.8–50.9 million for the BBC, with YouTube also ahead in October and November.
- The Barb measure counts a person as reached after three consecutive minutes of viewing across TVs, phones, tablets and computers.
- The BBC disputes the three‑minute yardstick and cites its preferred 15‑minute reach, averaging 47 million monthly in 2025 versus 40.8 million for YouTube, alongside 351 million BBC TV hours watched weekly.
- Analysts attribute YouTube’s rise to greater access on smart TVs and a surge in longer, higher‑production creator content that increasingly competes with traditional TV.
- The shift is feeding policy debates on the BBC’s charter and licence fee, with ministers weighing funding options, a planned rise to £181 in April, and potential rules to secure public‑service prominence on major platforms.
