ABC, CBS, FOX, NBC Lose 60% of Primetime Viewers
The four major U.S. broadcast networks—ABC, CBS, NBC, and Fox—have experienced a dramatic decline in primetime viewership, dropping over 60% since the 1980s. In the 1980s, these networks averaged 14-16 million viewers, but by the 2020s, this has fallen to around 4-6 million. The decline is attributed to the rise of cable, streaming services, cord-cutting, and shifting viewer habits. Live sports and event programming still attract large audiences, but regular entertainment programming now draws only a fraction of its former reach. This has led advertisers, affiliates, and studios to adapt strategies, with many scripted series designed for streaming first and broadcast as secondary.
The decline of linear TV viewership directly impacts the advertising industry, affecting ad pricing, targeting, and the shift of ad budgets to digital and streaming platforms.

Top 10 Cable Networks with Biggest Viewership Drops in 2025
Nielsen measurement data shows widespread, steep declines in cable TV viewership across 2025 as audiences shifted toward streaming, on-demand and short-form platforms. Justice Central experienced the largest fall (‑78% to ~17,000 daily viewers), while a range of niche and mainstream networks — including Merit TV, Family Entertainment TV, Viceland, ReelzChannel and USA Network — lost large shares of their audiences. The report highlights cord-cutting, the rise of free ad-supported streaming (FAST) and updated Nielsen methodologies as drivers revealing sharper declines than prior panel-only measures. Sports channels such as ESPN remained a partial exception due to live events. The results underscore continued advertiser and revenue migration away from linear TV and raise questions about the long-term viability and strategic pivots of smaller cable channels.
