FAST Channels: Free Streaming’s Growth Engine in 2025

Once a niche corner of the streaming world, FAST (Free Ad-Supported Streaming TV) channels have officially gone mainstream. If you’ve ever scrolled through Pluto TV, Tubi, or The Roku Channel, you’ve seen them in action—linear-style streaming channels that cost nothing to watch, because they’re funded by ads instead of subscriptions.

And in 2025? The FAST space isn’t just growing—it’s exploding. According to a recent Gracenote report, “audience engagement and interest from advertisers are rising, positioning FAST as the streaming industry’s latest growth opportunity.” Nearly half of U.S. households now tune in weekly, and projections put FAST viewership on track to top 115 million Americans in the near future.

With connected TV devices in roughly 80% of homes, free ad-supported streaming has officially cemented itself as a core part of how America watches TV. A recent Gracenote report notes that “audience engagement and interest from advertisers are rising, positioning FAST as the streaming industry’s latest growth opportunity”. In practice, nearly half of U.S. households now tune into FAST channels weekly, and industry estimates project FAST will reach over 115 million U.S. viewers soon. With connected TV devices in roughly 80% of U.S. homes, free ad-supported streaming has become a mainstream part of how Americans watch TV.

As audiences shift from cable to streaming, FAST channels are capturing viewers seeking cost-free content. About 51% of streamers say they plan to spend more time with FAST channels this year. In fact, roughly 25% of U.S. households already watch news or other programs on FAST channels. FAST viewers skew toward cord-cutters and younger adults: one survey found FAST news audiences were over 7× more likely to have cut cable and about 2× as likely to be age 18-34, compared to the average TV viewer. In short, FAST appeals to value-conscious, digital-first viewers who grew up streaming, making it an essential platform for reaching cord-cutters and young demos.

Content & Channels: From Reruns to Live Events

The FAST lineup has expanded dramatically. In the U.S., FAST channels went from roughly 100 in 2019 to over 1,600 by 2023. Leading platforms add new channels every month – for example, Samsung TV Plus alone offered about 700 FAST channels in the U.S. by early 2025. And these channels aren’t just old reruns: only about 13% of FAST programming dates before 1990, meaning most FAST content is relatively new or recently produced. Platforms are filling FAST with higher-quality library titles and even new programming.

Importantly, live and popular genres are driving growth. Sports and reality channels are proliferating on FAST. Between mid-2024 and early 2025, the number of sports-focused FAST channels more than doubled (105% increase). Many now stream live events – for example, FOX simulcast Super Bowl LIX free on Tubi in Feb 2025 – treating FAST as an extension of TV. A new Roku sports FAST channel launched in 2024 carries live MLB and Formula 1 games. Reality-TV FAST channels exploded even faster: their count grew 626% from mid-2024 to early 2025. Overall, FAST content is mirroring free TV: sports, reality, news and general entertainment dominate as they do on broadcast/sports channels.

Advertising on FAST: Bigger Budgets, Better Targeting

Marketers are responding by shifting ad dollars toward streaming and FAST. U.S. connected-TV (CTV) ad spend is projected to hit $32.6 billion in 2025 (nearly double 2021), and streaming TV is expected to be the fastest-growing ad category this year. FAST is a big part of that growth. Globally, FAST ad revenue is forecasted to roughly double by the end of the decade (from ~$8 billion in 2023 to ~$17 billion by 2029). Even within existing streaming platforms, ad-supported tiers are expanding – nearly every major streamer (Netflix, Disney+, Max, etc.) now offers a lower-priced ad tier. This has flooded the market with new ad inventory; in some cases it even temporarily lowers CPMs, since so many ads are available.

Crucially, FAST offers much richer targeting and measurement than old-school TV. Advertisers can use programmatic, data-driven buying on FAST platforms to reach specific audiences. For example, you can often target FAST viewers by geography, demographics or interests – precision that cable TV never allowed. Advanced ad tech (AI and machine learning) lets FAST channels serve contextual and addressable ads, tailoring commercials to the content and inferred mood of the viewer. Early experiments show opportunities like shoppable ads and interactive overlays on FAST, allowing viewers to click or scan to learn more.

Measurement is improving too. FAST platforms are rolling out cross-device attribution and incremental lift testing, so brands can track the real impact of FAST ads on conversions. In practice, most FAST ad buys now go through programmatic auctions, and the rising use of first-party data means advertisers get better audience insights while respecting privacy. In short, fast-emerging tools (AI-driven targeting, programmatic automation, advanced metrics) are making FAST a more accountable and precise medium for marketing.

Key Takeaways for Marketers

  • Include FAST in your media mix: Don’t overlook free streaming. Consumer eyeballs and ad dollars are moving here, so allocate part of your CTV/video budget to FAST. Many agencies note that buying FAST channels (or FAST-based package deals) can be a cost-effective way to reach streaming audiences. Consider experimenting with FAST placements or programmatic deals and measure the results.
  • Target smart: Use the targeting options FAST offers. Leverage audience segments, contextual signals and first-party data to place ads on channels where your buyers are. For example, you can often aim ads by location, interests or even the type of show (sports vs. reality). As third-party cookies fade, focus on contextual relevance: match ad creative to the viewing context on FAST for better engagement.
  • Match content to customers: Align your FAST buys with the content your audience loves. FAST channels now include major live sports, reality series and popular news programs. If you’re marketing a sports brand, running ads on FAST sports channels (e.g. live game streams) can capture passionate fans. If you target younger viewers, note that FAST news and entertainment channels tend to skew young. Choosing the right genre/channel category makes your ads more effective.
  • Optimize creative: Design ads for streaming. Interactive formats (shoppable ads, overlay banners, QR codes) are trending on FAST. And remember ad load: viewers expect fewer, more relevant ads on streaming. Keep spots shorter and highly engaging, and test interactive elements to drive action. Always ensure brand and message are immediately clear, since FAST viewers are often multitasking or casually browsing.
  • Measure and iterate: Track FAST campaigns with granular metrics. Use incremental lift and attribution tools to see how FAST ads drive incremental reach or sales. Compare FAST campaign results to your overall media mix and shift budgets to the best performers. Because FAST is still evolving, test-and-learn is key: run pilot campaigns, analyze which channels and formats work, and refine your strategy.

FAST channels are no longer a fringe phenomenon – by 2025 they’re a major media ecosystem. Marketers who embrace FAST now, using data-driven targeting and integrating streaming into their plans, will capture viewers that others miss.
