Roku, Inc. operates through two primary segments: Platform and Devices. The Platform segment generates the vast majority of the company's revenue through digital video advertising, streaming service distribution, and its proprietary ad-supported streaming service, The Roku Channel. The Devices segment encompasses the sale of Roku-branded streaming players, audio products, and smart home devices, alongside licensing arrangements with TV manufacturers for Roku TV models. By controlling the underlying operating system, Roku effectively aggregates content from various publishers and monetizes user engagement through targeted advertising and subscription revenue sharing. While primarily focused on the United States, the company has been expanding its geographic footprint across Latin America and Europe.
