Designated Market Areas (DMAs) represent the foundational geographic segmentation for television audience measurement and media distribution across the United States, with 210 distinct DMAs covering the entire continental U.S., Hawaii, and parts of Alaska. The DMA media landscape encompasses both public and private broadcasting entities, where private commercial stations dominate audience reach and advertising revenue while public broadcasters through PBS and NPR provide non-commercial educational and informational content. Private media ownership has become increasingly concentrated, with major corporations like Nexstar Media Group operating over 200 stations across 116 markets and Sinclair Broadcast Group controlling 178 stations in 81 markets, creating significant disparities in content diversity and local news production capabilities. Public broadcasting stations, numbering approximately 350 for television and 1,136 for radio, serve crucial informational roles particularly in smaller and rural markets where they receive between 25 to 50 percent of their operational revenue from Corporation for Public Broadcasting (CPB) federal appropriations, though this funding faces ongoing political challenges and reductions.
The Federal Communications Commission (FCC) serves as the primary regulatory body governing the DMA media landscape, enforcing ownership caps that limit any single entity to reach no more than 39% of U.S. television households, maintaining local ownership restrictions limiting common ownership to two television stations per DMA with prohibitions on owning two top-four rated stations, and implementing the Dual Network Rule preventing mergers among the Big Four broadcast networks (ABC, CBS, NBC, Fox). Significant regulatory developments include the 2022 Quadrennial Review examining whether existing ownership rules remain necessary in light of digital competition, the July 2025 Eighth Circuit court decision vacating portions of the Local Television Ownership Rule's Top Four Prohibition, and ongoing debates regarding deregulation to allow broadcasters greater scale to compete with streaming giants and digital platforms. The FCC also maintains authority over indecency standards, content requirements, and licensing procedures, though recent court challenges have questioned whether license denial based on viewpoint constitutes unconstitutional government regulation.
Digital transformation has fundamentally restructured the DMA media landscape, with broadband internet penetration reaching 79% of U.S. adults and 84.9% of households owning at least one TV-connected device as of 2023. Traditional broadcast and cable television consumption has declined precipitously, with only 29% of U.S. adults regularly watching local TV news in 2022 compared to 46% in 2016, while streaming services and social media platforms have captured dominant audience shares through on-demand content and algorithm-driven personalization. Over-the-top (OTT) platforms and connected TV viewership have grown substantially, with 35.5% of U.S. TV households accessing content solely through broadband internet connections, fundamentally challenging the traditional DMA-based broadcast model. Historical shifts including the 1996 Telecommunications Act enabling unprecedented media consolidation, the 2009 digital television transition eliminating analog broadcasts, the rise of cable television beginning in the 1950s, and the explosive growth of streaming services from 2015 onward have progressively eroded local broadcast television's monopoly and forced regulatory reconsideration of rules designed for an analog broadcasting era.

Media consumption within Designated Market Areas (DMAs) shows significant evolution in 2025, though comprehensive DMA-specific penetration and spending data is limited in current research. DMAs, which are proprietary geographic regions defined by Nielsen that group counties based on television viewing areas, remain essential units for measuring local TV viewership despite the digital transformation of media consumption.
Television continues to dominate media consumption within DMAs, accounting for 28.07 hours per week of usage, including live, digital, streaming, and OTT video platforms. However, the landscape is rapidly fragmenting. In 2024, the average consumer spent 8.17 hours per day with media, up from 7.36 hours in 2019, though this growth is plateauing.
Digital media penetration has reached a critical threshold, with its share rising to 39.7% globally in 2024, up from 37.3% in 2023. In 11 of the top 20 markets, digital media usage now accounts for over half of all media consumption. Mobile video experienced the most substantial gains, increasing 16.7% in 2024, while film and home video saw the fastest growth rate at 10.4% due to direct-to-streaming releases and blockbuster films.
A concerning trend for advertisers is that consumers spent only 52.7% of their time on ad-supported media in 2024, down from 55.5% in 2019, indicating a shift toward subscription-based and ad-free platforms.
While specific DMA-level advertising spend data is not available in current sources, the broader trends indicate significant shifts in advertiser priorities. Traditional media usage is declining, yet these channels still offer audience compositions larger than some currently favored digital channels like influencer marketing and content marketing. This creates a paradox for media buyers who must balance reach with targeting precision.
The challenge for advertisers operating within DMA frameworks is acute: they want to reach specific populations—such as affluent demographic groups in fast-growing suburban areas—but are constrained by having to purchase broad DMA-wide inventory that includes thousands of irrelevant households. This inefficiency stems from the mismatch between modern data-driven targeting capabilities and the anachronistic geographic boundaries that define DMAs.
The viewing landscape shows dramatic shifts away from traditional linear consumption patterns. US audiences are competing for an average of six hours of daily media and entertainment time per person, and this number has reached saturation and is not growing. Looking across generations, preferences are shifting decisively away from pay TV and toward streaming video services, social video platforms, and gaming.
Time spent with digital video is increasing by 9 minutes in 2025, but losses in traditional TV viewing almost fully offset that gain. Overall time with video is expected to decline starting in 2026. More than 1 in 4 Americans consume 5+ hours of media per day, with all age groups showing at least this proportion consuming that amount during weekends.
The fragmentation extends to device usage as well, with consumers using different devices to access content throughout the day. This multi-device consumption pattern, combined with the emergence of simultaneous multi-device usage, further complicates how advertisers can effectively reach audiences within traditional DMA structures.
A critical development for DMAs is the projected 0.3% decline in overall media usage growth in 2025—the first drop since 2009. This decline indicates that gains in digital media are no longer compensating for declines in traditional media use. Media consumption in odd-numbered years tends to underperform compared to even-numbered years due to the absence of major televised events like sports competitions and elections that typically drive viewership.
The fundamental issue facing DMA-based measurement is that metropolitan areas have sprawled across DMA lines, and suburbs that were once farmland are now population centers with distinct identities often ignored by "local" TV news delivered from distant DMA hub cities. Meanwhile, IP-based platforms and technologies like ATSC 3.0 make it technically possible to tailor content and advertising to neighborhoods and even ZIP+4 clusters, creating a stark mismatch between regulatory frameworks anchored to DMAs and modern targeting capabilities.
For broadcasters and networks, DMAs remain key for determining local audience measurement, informing programming decisions, and understanding market size and reach. Each DMA is ranked based on the number of TV households, allowing networks to make informed decisions on ad inventory pricing. However, the growing disconnect between DMA boundaries and actual viewing patterns, combined with the rise of streaming and social video platforms that operate outside traditional geographic constraints, suggests that while DMAs remain relevant for local TV measurement, their utility as a comprehensive framework for understanding modern media consumption is increasingly limited.
Media trust levels in the U.S. have reached a new low, with only 28% of Americans expressing a "great deal" or "fair amount" of trust in newspapers, television, and radio to report news fully, accurately, and fairly.
| Demographic | Description |
|---|---|
| Age Group | Media trust is higher among older adults (43% for 65+ years old), decreasing with younger demographics. |
| Gender | No significant gender differences in media trust reported. |
| Region | Trust levels can vary by region but not extensively documented. |
| Socioeconomic Status | Influences media access and trust, with higher socioeconomic groups potentially having broader access to diverse media sources. |
No specific DMA radio listening trends or average times were identified in the provided results. Global and DMA-specific radio data (such as urban vs. rural divides, daily hours, or demographic splits) are unavailable in these sources.
No explicit podcast consumption statistics (hourly averages, demographic insights, or DMA breakdowns) were found in the available sources. Podcast trends, especially in DMAs, remain a gap in this dataset.
Note: DMA-specific data (e.g., Nielsen local reports, FCC filings, or local radio/streaming figures) are not included in the above sources and would require further research for granular insights by market tier, urban/rural splits, or micro-level device, podcast, and radio data.
