Why Should You Advertise on Roku?
Roku can seem broad, but it breaks down into two key pieces: the Roku platform and the Roku Channel.
The Roku platform is the whole ecosystem, Roku OS powers smart TVs and streaming players, hosting apps like Netflix and Disney+. In December 2025, 21.2% of all TV viewing happened on Roku-powered devices, and Roku stands as a dominant platform integrator with 70%+ penetration of all U.S. internet-connected households, working across virtually every major DSP.
The Roku Channel is Roku’s free, ad-supported streaming service that lives within that ecosystem.
Meet Your Audience: The Browsers
Roku viewers behave like channel surfers in a streaming wrapper browsing, discovering, and leaning back.
What makes them valuable? They’re the people traditional TV lost.
- The median Roku household streams across 9 different apps, 3 of which are free. The average home adds 4 new apps and drops 4 per year. Streamers churn through apps, not through Roku.
- 90% of Roku Channel engagement starts from the Roku home screen, meaning viewers aren’t seeking out the app, they’re discovering content right from the front door.
- Ads in free streaming get the same visual attention as ads in paid streaming environments like Disney+ and Peacock, less than 1 percentage point difference, per Roku + MAGNA research.
- 59% of consumers now use at least one free ad-supported streaming service regularly, and the global FAST audience is expected to hit 1.1 billion by 2029.

How to Measure
Roku gives you the biggest screen, the most engaged audience, and the richest targeting data in streaming. [cognition] is the platform that lets you activate it, measure what happened, and prove it worked, all in one place.
We break our Measurement Studio into three layers:
- Reporting is your receipt. Where did your money go, how many impressions did you get, and what was your CPM? Across every tactic and every channel, in one unified view.
- Attribution is one-to-one. I served an ad, they bought a thing. Cognition’s Headless Analytics Tag stitches the full journey from TV exposure to website action to purchase, so you can calculate actual ROAS, not just guess at it.
- Measurement is directional feedback. The Headless Analytics Tag connects ad exposure to real-world outcomes, whether that’s foot traffic to a physical location, key actions on your website, or lift in the markets where you’re running media.
