A new industry group is targeting the disconnect between how children use digital media and how advertisers track their behavior. Billions in ad spend and compliance risks are at stake. The initiative seeks to modernize measurement standards.
Media and publishing professionals focused on digital audiences now face a growing challenge: the gap between how children actually consume media and how the advertising industry measures that activity. The Advertising Research Foundation's Coalition for Innovative Media Measurement (CIMM) has announced a new task force to address this disconnect, citing urgent business, legal, and operational consequences for publishers, platforms, and advertisers.
According to a primer released with the announcement, children’s media habits have shifted decisively toward fragmented, platform-driven digital environments. However, measurement systems have not kept pace, resulting in a widening gap between where children spend their time and where the industry has reliable data. CIMM consultant and former Disney executive Emily Horgan said this measurement gap is now limiting investment, distorting incentives, and threatening the long-term sustainability of the children’s media ecosystem. The report also points to significant economic and legal risks, including compliance with regulations such as COPA and the impact on billions of dollars in advertising spend.
The task force will bring together media platforms, ad tech companies, supply chain and measurement providers, and ad industry representatives to collaborate on new measurement initiatives. The goal is to create standards that better reflect how children engage with media today. The report highlights several key challenges: traditional panels, while offering high-quality, consent-based data, lose statistical power as audiences fragment by age, platform, and content type. Big data sources like Smart TV ACR, set-top box data, and server logs provide scale but rarely identify child viewers, as children often lack personal devices or accounts. Most video platforms offer limited visibility into children’s viewing, especially for those under 13, creating data gaps across the ecosystem. Some stakeholders question whether current platform policies are more restrictive than required by law, suggesting there may be room to clarify what types of measurement are permissible.
Another major blind spot is gaming platforms, which now account for a significant share of children’s media time but remain virtually unmeasured, especially for publishers seeking a unified view of consumption. The report also notes that economic incentives in ad tech often prioritize scale over accuracy, further distorting the supply chain. For example, studies show that datasets identifying households with children are only 42% accurate.
This move by CIMM comes as the industry continues to grapple with evolving measurement standards. Recent developments, such as the exit of major providers from accreditation processes, have highlighted the volatility in ad metrics and the need for more reliable cross-platform measurement, as discussed in coverage of changes in ad currency accreditation.
