Roku

Dominant CTV platform and OS provider in the U.S., with leading market share in streaming hours and active accounts; a top-tier CTV advertising destination

Roku is a publicly traded streaming platform company that operates the #1 TV streaming platform in the United States by active accounts and streaming hours. Founded in 2002 and headquartered in San Jose, California, Roku's operating system is embedded in millions of smart TVs and proprietary streaming devices, giving it unparalleled reach into living rooms across North America and internationally. The company serves as a central aggregator for hundreds of streaming channels and services, including Netflix, Disney+, Hulu, and its own free ad-supported service, The Roku Channel. Roku's advertising business, known as the Roku Platform, is a cornerstone of its revenue model and a major force in the connected TV (CTV) advertising landscape. Advertisers can reach Roku's massive audience through OneView, its demand-side platform (DSP), as well as through direct ad sales on The Roku Channel and across its network of ad-supported streaming apps. Roku offers advanced targeting, measurement, and attribution capabilities, making it a preferred partner for brands seeking to reach cord-cutters and streaming-first audiences at scale. In the AdTech ecosystem, Roku occupies a uniquely powerful position as both an OS-level gatekeeper and a media owner, giving it first-party data advantages that are increasingly valuable in a cookieless advertising environment. Its acquisition of Nielsen's Advanced Video Advertising business and dataxu (now OneView) significantly expanded its programmatic and data capabilities. Roku competes with Amazon Fire TV, Google TV/Android TV, and Apple TV for device and OS market share, while also competing with major streaming platforms and CTV ad networks for advertising dollars.
