Television audiences at NASCAR are experiencing a moment of change with the introduction of a new measurement system that combines traditional technology with innovation. Starting in September 2025, Nielsen Media Research has implemented the Big Data + Panel model, which integrates data from televisions and cable boxes with conventional methods.
Until now, Nielsen had used a system based on household panels, where some homes manually recorded what they watched. This system collected data from about 42,000 households to approximate audience analysis based on different demographics. With the new methodology, more information is included, providing a more complete picture of viewers’ viewing habits.
This new approach facilitates the collection of viewing habit data through connected devices, although it has its limitations. Big Data collects information on which channels are watched and the time spent, but does not identify who the viewer is. To address this, Nielsen uses artificial intelligence to adjust the data with demographic probabilities based on historical patterns.
An example of its impact can be observed in the latest races. The NASCAR Cup Series at Nashville Superspeedway reached 1.655 million viewers according to the traditional system, a 12% decrease from the previous year. It is important to note that the world of audiences has changed, and therefore year-to-year comparisons can be misleading.
In contrast, for the NASCAR O’Reilly Auto Parts Series, the data shows a 14% increase with 1.123 million viewers compared to last year. The results show that despite the measurement challenges with Big Data, interest in NASCAR remains significant, especially on streaming platforms where there has been an increase in the viewer group aged 18 to 49 years.
