Introduction to Nielsen's Methodology Change
On September 1, 2025, Nielsen implemented a significant change to its ratings methodology, introducing a "big data plus panel" measurement system for live programming. This update coincided with the commencement of the NFL season and aims to provide a more accurate depiction of viewership by integrating data from millions of households equipped with smart TVs and streaming devices alongside traditional panel sampling.
Impact on Sports Programming
The initial results of this new measurement system indicate notable increases in viewership for various sports broadcasts. For instance, Fox Sports reported that its first three weekends of NFL games averaged 22.42 million viewers, reflecting a 14 percent increase compared to the previous year’s panel-only ratings. Similarly, Amazon's Thursday Night Football broadcasts experienced viewership gains of 19 and 23 percent. Other networks, including ABC/ESPN, CBS, and NBC, also reported growth in their sports programming, particularly in college football, which is experiencing its best early-season ratings since the mid-2000s.
The new methodology has shown that, where direct comparisons are possible, the big data inclusion captures approximately one million more viewers for certain games. For example, NBC's opening weekend NFL games averaged 22.5 million viewers with the new measurement, compared to 21.5 million under the previous system.
Broader Implications for Television Ratings
Nielsen's rollout of the big data plus panel measurement is expected to extend to all Nielsen-measured programming with the official start of the 2025-26 TV season on September 22. This transition raises questions about how the new methodology will affect viewership metrics for non-sports programming, such as comedies and dramas, as the impact becomes clearer in the coming weeks.
Criticism and Response
The timing of Nielsen's new system rollout follows criticism from the NFL regarding potential undercounting of viewers. This criticism may have influenced Nielsen's decision to enhance its measurement approach, aiming to provide a more comprehensive view of audience engagement.
Conflicting Reports & Gaps
While the new ratings methodology has shown promising results for sports programming, it remains to be seen how it will affect other genres. The effectiveness of the big data plus panel measurement in capturing viewership for comedies and dramas is still under evaluation, and Nielsen has yet to release comprehensive data on these categories.

Conclusion
Nielsen's introduction of the big data plus panel measurement system marks a pivotal shift in how television viewership is quantified, particularly for sports programming. As the new methodology continues to roll out, its broader implications for the television landscape will become increasingly apparent, potentially reshaping how networks approach content and advertising strategies.
