Roku operates a comprehensive TV streaming platform and ecosystem that connects viewers, content partners, and advertisers across North America and select international markets. The company generates revenue through two primary segments: a Devices segment that sells Roku-branded streaming devices, TVs, audio products, and smart home equipment, all running Roku's proprietary TV OS; and a Platform segment that monetizes viewer engagement through digital advertising, owned streaming services, subscription revenue sharing, and fees from content partners. Roku's business model focuses on achieving scale through an accessible device lineup, driving engagement via content aggregation and platform innovations, and monetizing that engaged audience through targeted advertising to both direct advertisers and programmatic buyers, as well as revenue shares from content partners distributing through various streaming models.
