Roku, Inc. and Nielsen announced that as of October 2021, Roku has now enabled publishers to measure channel content on Roku devices within Nielsen Digital Content Ratings (DCR). Digital Content Ratings provides access to deduplicated reach and demographic insights for channels on Roku devices to identify which programs most effectively reach key audiences. This increase in coverage helps content owners and advertisers navigate the expanding world of TV streaming and is a major milestone on the path to Nielsen ONE, Nielsen's transformative, cross-media solution that will enable advertisers and publishers to transact using a single metric across linear and digital television. Nielsen will enable publishers to measure content across Roku's 55.1 million active accounts (as of Second Quarter 2021).

Nielsen Digital Content Ratings (DCR) provides comprehensive audience measurement of digital content consumption, including streaming video, static web pages and mobile apps, across computer, mobile and TV streaming devices. DCR is a census-based, panel- calibrated solution that provides syndicated, granular reach and volumetric reporting to provide advertisers and publishers with a robust understanding of who consumes content across the digital media landscape.
