NASCAR's viewership numbers are in a state of flux, and it's all about the methodology. The recent NASCAR Cup Series race in Chicagoland has brought this issue to the forefront, highlighting the importance of the chosen measurement system. The race averaged 2.1 million viewers on TNT Sports using the 'Big Data + Panel' methodology, while the old panel-only metric reported 2.35 million viewers. This discrepancy is not an isolated incident, as it marks the second time in as many weeks that the 'Big Data' figure has trailed its panel-only equivalent on TNT.
The 'Big Data + Panel' approach, which integrates data from smart TVs, set-top boxes, and select providers' first-party data, has generally boosted sports viewership. However, NASCAR is an exception, with its linear television viewership consistently lower on a 'Big Data' basis compared to the old panel-only metric. This trend is particularly intriguing, as there's no clear explanation for why NASCAR's linear viewership would be disadvantaged under the new system.
The race in Chicagoland saw a 3% increase in viewership on a 'Big Data + Panel' basis compared to last year's Chicago Street Race, but a 14% increase on a panel-only basis. This discrepancy is not unique to Chicagoland; it has been observed across five races on the streaming platform Prime Video, where 'Big Data' outperformed 'panel-only' by 15%.
NASCAR's decision to stop reporting 'Big Data + Panel' figures for its races after the Fox Sports portion of the season is notable. The sport is now the only major league or network publicizing the 'panel-only' results. This move raises questions about the potential divergence between the two measurement systems and whether other leagues might face similar challenges.
The O'Reilly Auto Parts Series race in Chicagoland, which was delayed by weather, averaged a meager 629,000 viewers on CW. This low viewership highlights the impact of external factors on race attendance and the importance of accurate measurement systems in assessing the success of sporting events.
In conclusion, the choice of measurement system significantly influences the perceived success of NASCAR races. The 'Big Data + Panel' methodology, while generally beneficial for sports viewership, presents unique challenges for NASCAR's linear television audience. As the sport continues to navigate this transition, it will be fascinating to see how viewership trends evolve and whether the 'panel-only' results can truly reflect the popularity of these races.
