Here are the most popular streaming services in 2025 — ranked two ways because “popular” can mean different things (paid subscribers worldwide vs. U.S. viewing share / time spent).

Top streaming services by global paid subscribers (approx., 2025)

• Netflix — largest paid base (roughly 280–310 million paid memberships in 2025, depending on the quarter/estimate). (spglobal.com, cnbc.com)
• Amazon Prime Video (via Amazon Prime) — one of the biggest global footprints (Prime membership/Prime Video reach measured in the low‑hundreds of millions; Prime Video alone reaches 100M+ viewing accounts and Amazon reports ~130M U.S. customers watching Prime Video with ads). (evoca.tv, latimes.com)
• Disney+ (plus Hulu in some company totals) — ~125–126 million Disney+ paid subscribers in early 2025 (Disney reports Disney+ and Hulu together when reporting some totals). (thewaltdisneycompany.com, thewrap.com)
• Max (Warner Bros. Discovery’s streaming service) — ~115–120 million combined streaming subscribers as of late‑2024/early‑2025 (WBD reported ~116.9M and is targeting 150M by end of 2026). (cnbc.com, brecorder.com)
• Paramount+ — ~79 million subscribers (Q1 2025 reported). (ir.paramount.com)
• Large China SVODs (Tencent Video, iQIYI, Youku) — each ranks among the global leaders because of China’s huge market (exact public reporting and reckoning differs by company/period). (See Statista / regional reports for China platform detail.) (statista.com, reuters.com)

Top services by U.S. viewing share / time spent (May 2025 Nielsen “The Gauge” snapshot)

• YouTube — largest share of U.S. TV viewing among streamers (about 12–12.5% of total TV time in spring 2025). (nielsen.com, cnbc.com)
• Netflix — another leading share of U.S. viewing (single‑digit share but still top among traditional SVODs). (nielsen.com)
• Disney (Disney+/Hulu/ESPN cross‑company viewing) and Amazon Prime Video — next in line by aggregate viewing share. Nielsen’s monthly Gauge shows free/ad‑supported FAST services (Roku Channel, Pluto TV, Tubi) also growing fast. (nielsen.com, thewrap.com)

Important notes

• Metrics differ: companies report different things (paid memberships, paying subscribers, accounts, monthly active viewers, or “viewing accounts”), and some firms (Netflix, Disney) have shifted how — or when — they disclose subscriber totals. That makes exact rankings sensitive to the metric and date used. (cnbc.com, theverge.com)
• Free/ad‑supported services and FAST channels (The Roku Channel, Pluto TV, Tubi, Freevee, etc.) have surged in viewing time even when their paid‑subscriber counts are lower. Nielsen’s 2025 data shows streaming overall surpassed combined broadcast + cable viewing in May 2025. (nielsen.com)

If you want a concise “Top 10” by one specific metric (global paid subscribers or U.S. viewing share) I can produce that with the latest public-quarter numbers and source citations. Which metric would you prefer me to use?
