Global Radio Audience Measurement: The Race Toward Hybridization in the Global Audio Landscape

In a radio landscape transformed by new listening habits, audience measurement is more critical than ever for broadcasters and advertisers. While radio remains a powerful local medium, the ways in which it is consumed are changing and becoming more complex—and so is the way it is measured: research firms are developing hybrid systems that combine self-reported data with automated tracking. 

The European radio industry does not speak with one voice when it comes to counting its listeners. While media audience measurement is often overseen by a Joint Industry Committee (JIC)—a shared governance structure involving broadcasters, agencies, and advertisers—which serves as a standard for transparency, the methods chosen for these studies vary from one region to another. They sometimes rely on self-reported data (verbal and/or written), sometimes on automated methods, and are moving toward an increasingly hybrid approach.

The European landscape: between tradition and technological disruption

In the United Kingdom, RAJAR (Radio Joint Audience Research) has thus shifted since 2021 to a system that relies primarily on self-reporting, with a core group of 60,000 people filling out listening diaries, supplemented by a passive panel of 5,000 individuals equipped with the MediaCell smartphone app for automatic measurement. This provides the radio market with a quarterly indicator of weekly reach for live broadcasts over the air and via streaming, covering at least 300 public and private stations, including regional ones.

In Germany, the approach favored by AGMA (Arbeitsgemeinschaft Media Analyse) is one of convergence under the “ma Audio” label, which aims to measure audio in its entirety. The system combines three distinct sources: 65,000 interviews, conducted by telephone (CATI) and online (CAWI, 8,000 by 2025), server data (logs) to specifically measure streaming, as well as listening diaries on audio consumption to cross-reference the data. The objective is clear: to cover the entire ecosystem, from FM to DAB+ to the web. The method provides daily, weekly, and biweekly coverage for 200 stations regarding their live broadcasts across all channels, as well as for web radio and music streaming platforms at the level of each German state. This study is published twice a year.

Italy, for its part, is embarking on a major turning point with the return in 2025 of Audiradio, the audience measurement organization that was dissolved in 2011 following disagreements among stakeholders in the radio industry. Its system promises greater granularity by combining telephone surveys with software solutions (SDKs) directly integrated to capture digital streams, in order to provide quarterly performance data for 250 radio stations.

It is in the Netherlands that audience measurement has recently undergone the most radical evolution to offer the market cross-media measurement across TV, digital, radio, and print. The country transitioned from listening diaries to automatic measurement in early 2023, joining Sweden, Norway, Iceland, and Switzerland in Europe, as well as North America, in adopting this automated system. Through the MediaCell+ system, listening is tracked in real time on the smartphones of 3,100 panelists. It is worth noting that paper-based listening diaries have been retained on a limited basis to study younger audiences. Ultimately, this measurement system delivers weekly results for the live broadcasts of 80 stations, primarily national ones.

In Belgium, a brand-new approach is being explored. The CIM (Media Information Center), which is responsible for measuring audiences for the country’s major media outlets, has begun transitioning from siloed measurements to cross-media measurement. The new CIM ONE study promises to capture all media consumption through panels equipped with people meters—including the MediaCell and RealityMine apps—listening diaries to track listening durations, and Census data for audio. The system is scheduled to go live in 2027.

Outside Europe, the hybrid system is also becoming the standard for measurement. In Australia, for example, Radio 360° has been combining three types of data since mid-2023: listening diaries from 50,000 respondents to provide radio audience levels, data from logs for online listening, and 2,000 panelists equipped with watches to refine the results. Results: weekly coverage of live radio stations across five regions, published eight times a year. 

Horizon 2027 in France 

The French system is currently based on a dual-source approach. The EAR audience study, which draws on 100,000 telephone interviews (CATI)—an extremely high volume compared to its neighbors—enables the maintenance of a dual level of granularity to provide daily, national, and local audience figures. Where other countries struggle to accurately measure local audiences using automated tools, France is able to produce audience data for nearly a hundred metropolitan areas.

At the same time, since 2022, France has offered the EAR Insights study, based on a panel of 6,000 people equipped with the RateOnAir meter, which enables precise measurement of listening behavior across all content and offerings from subscribing radio stations, over a week or a month, by distinct listening mode (FM, DAB+, live radio, replay, podcasts, and web radio). A uniquely French feature is the inclusion of non-linear and 100% digital usage in its measurement, which is still largely excluded from international systems.

Despite this robustness, the French model must evolve to address two challenges. On the one hand, the decline in telephone reach; on the other, the erosion of terrestrial radio consumption in favor of streaming and podcasts.

Médiamétrie’s strategy for 2027 is centered on a two-step transition. First, it will strengthen its core measurement methods. The self-reporting component will become “multimodal.” Starting in September 2026, approximately one-third of interviews will be conducted online (CAWI) using a simplified questionnaire optimized for mobile devices to better align with respondents’ habits. At the same time, the automated component will be enhanced by a new meter—a smartwatch—that is even better suited to panelists’ lifestyles, ensuring comfortable wear throughout the day and tracking every movement. 

By 2027, the results of all this work will enable us to offer a robust 3D hybrid model tailored to the specific characteristics of the French market. The ultimate goal is to merge proven solutions into a single, simplified measurement system. This model will rest on several pillars: self-reported measurement, via CATI/CAWI surveys, to collect radio consumption data from a large number of respondents, thereby maintaining robustness and geographic precision; automatic measurement, using smartwatches, to track changes in consumption within the same population over the long term; and, in a second phase, return-path data to measure all digital consumption, including the most fragmented forms. This shift toward comprehensive audio measurement aims to provide advertisers, agencies, media houses, and publishers with a complete view of audio consumption, regardless of the medium, while keeping measurement production costs under control.
