comScore

One of the leading global audience measurement and analytics providers, serving as an alternative currency to Nielsen for cross-platform media measurement

comScore is a global information and analytics company headquartered in Reston, Virginia, specializing in audience measurement, advertising verification, and consumer behavior analytics across digital, television, and streaming platforms. Founded in 1999 and publicly traded, comScore serves media companies, advertisers, agencies, and publishers by providing the data infrastructure needed to plan, transact, and evaluate media investments in an increasingly fragmented media landscape. The company's core offerings span digital audience measurement, cross-platform measurement, TV and streaming ratings, advertising effectiveness, and brand safety solutions. comScore's Unified Digital Measurement (UDM) methodology and its cross-platform capabilities position it as a critical currency provider for the media and advertising ecosystem, enabling clients to understand deduplicated audiences across devices and screens. Its products are used by thousands of clients globally to make informed decisions about content strategy, ad spend allocation, and audience targeting. In the AdTech ecosystem, comScore competes with Nielsen, Kantar, and other measurement firms, and has worked to establish itself as an alternative currency for TV and digital advertising transactions. The company has faced regulatory and financial challenges over the years, including an SEC investigation and restatement of financials, but has continued to operate and invest in its measurement infrastructure. comScore remains a significant player in the media measurement space, particularly as the industry navigates the shift from linear TV to streaming and the deprecation of third-party cookies.
