Linear television remains a $120 billion global advertising market despite streaming capturing 49% of US viewing time as of July 2026. Industry players are increasingly adopting programmatic tools and agentic AI to modernize the buying of traditional scheduled inventory.
The resilience of linear spending despite a massive shift in viewing habits highlights a significant lag between audience behavior and budget allocation. Advertisers remain anchored to linear by the high frequency of exposures and the unique ability of broadcast to aggregate large, simultaneous audiences for live events. However, the rapid adoption of programmatic tools by players like Comcast Advertising and Magnite suggests the industry is finally modernizing the buying process to match digital efficiency. As measurement disputes between the Video Advertising Bureau and Nielsen continue, the industry must reconcile disparate data sets to justify these high spend levels. Watch for the impact of Nielsen's seven currency changes this autumn to see if they stabilize linear's perceived value.
As networks look to optimize their remaining linear inventory, many are turning to independent agency programmatic strategy to reduce waste and improve yield management. Meanwhile, CTV advertising spend continues to climb as programmatic supply expands across premium streaming environments.
The global linear TV ad market is projected to reach $120.3 billion in 2026, despite streaming capturing 49% of US viewing time. This resilience persists because live sports and news continue to aggregate large, simultaneous audiences, keeping linear inventory highly attractive to major advertisers even as traditional broadcast viewership declines.
The global linear TV ad market is forecasted to reach $120.3 billion in 2026, a slight decline from the $123.5 billion recorded in 2025.
Advertisers remain anchored to linear TV due to the high frequency of exposures and the unique ability of broadcast and cable to aggregate large, simultaneous audiences for live events like sports and news.
Companies like Magnite, ITN, Comcast Advertising, and AMC Global Media are using AI agents and programmatic private marketplaces to reduce buying cycles and improve digital efficiency.
According to Nielsen's The Gauge, broadcast and cable combined fell to 38.2% of US television time by July 2026.
