Nielsen at this time introduced a pilot program utilizing proprietary wearable units to measure co-viewing throughout main dwell tv occasions, starting with Tremendous Bowl LX on February 8. The measurement firm positions the initiative as an enhancement to its recently-implemented Huge Information + Panel rankings system, addressing a persistent problem in capturing whole viewership when a number of individuals watch the identical display.
The pilot launches lower than a 12 months after Nielsen ended its traditional panel-only TV ratings system, transitioning to a hybrid methodology that mixes knowledge from roughly 101,000 individuals throughout 42,000 households with inputs from about 45 million households and 75 million units. In response to Nielsen CEO Karthik Rao, the co-viewing methodology “builds on that mission, alongside our latest enhancements with Huge Information + Panel, out of dwelling enlargement, dwell streaming measurement and our wearable units.”
The wearable measurement units resemble smartwatches and are worn on the wrists of Nielsen panelists. These units seize audio from tv occasions, reveals, and films by way of passive measurement know-how that eliminates the necessity for formal login procedures. The audio seize method represents a technical shift from energetic panel participation towards automated detection of viewing habits.
Nielsen obtained Media Ranking Council accreditation for its Big Data + Panel measurement in January 2025, marking the primary time the group permitted a nationwide TV measurement system combining conventional panel knowledge with large-scale gadget info. The MRC accreditation adopted years of business debate about measurement methodology transitions, with Nielsen initially promising the change in 2020 earlier than extending the timeline following resistance from advertisers and businesses.
The co-viewing pilot program will proceed past Tremendous Bowl LX to cowl high-profile sports activities and leisure dwell occasions in the course of the first half of 2026. Nielsen will launch preliminary pilot outcomes a number of weeks after delivering its ultimate Huge Information + Panel rankings, which stay the official foreign money for promoting transactions. The pilot knowledge will likely be made out there to Nielsen shoppers following the supply of ordinary rankings, with shoppers permitted to share findings publicly.
This measurement enhancement addresses a basic limitation in tv viewers monitoring. When a number of family members watch the identical tv display concurrently, conventional measurement methods battle to seize the total viewing viewers. Reside occasions notably undergo from this measurement hole, as sports activities programming and main leisure broadcasts incessantly generate group viewing habits that single-viewer metrics fail to symbolize precisely.
The co-viewing methodology differs from commonplace panel measurement by incorporating device-based monitoring slightly than relying solely on family member self-reporting.

These developments replicate broader business strain to precisely measure fragmented viewing throughout broadcast, cable, streaming, and out-of-home contexts.
The technical implementation of co-viewing measurement includes matching audio fingerprints from wearable units in opposition to programming databases to find out viewing presence. This method differs from Huge Information + Panel’s device-level monitoring, which captures what content material performs on televisions and streaming units however can not definitively decide who within the family was truly watching. Wearables bridge that hole by offering person-level verification tied to particular content material.
The pilot timing coincides with important measurement challenges for Tremendous Bowl promoting. Consumer spending around Super Bowl LVIII reached $18.6 billion throughout meals, drinks, attire, décor, and associated gadgets, in line with Nationwide Retail Federation figures. Greater than 127 million viewers watched Tremendous Bowl LIX on February 9, 2025, establishing the sport as promoting’s largest single-day viewers alternative. Correct co-viewing knowledge may considerably affect these viewership figures by capturing extra family members watching alongside main viewers.
Nielsen’s measurement infrastructure has expanded considerably by way of partnerships with main platforms. The corporate deepened its relationship with Roku in December 2025, integrating Roku’s viewing knowledge into Huge Information + Panel measurement for each linear and streaming rankings.

The measurement methodology builds on Nielsen’s proprietary gadget ecosystem slightly than counting on shopper wearables from third-party producers. This method provides Nielsen direct management over gadget specs, knowledge assortment protocols, and high quality assurance processes. Panelists obtain units particularly designed for measurement functions slightly than utilizing commercially out there smartwatches or health trackers.
Nielsen’s announcement emphasised that co-viewing estimates from the pilot program is not going to instantly combine into Huge Information + Panel rankings. The info stays experimental slightly than turning into official foreign money for promoting transactions. This phased method permits Nielsen to validate methodology, deal with technical points, and construct business confidence earlier than incorporating co-viewing changes into transactional rankings.
The corporate plans to supply extra affect knowledge to shoppers later in 2026 earlier than absolutely implementing the co-viewing methodology into its advertising and marketing intelligence product suite. Nielsen targets incorporating co-viewing into foreign money measurement for the 2026-2027 tv season, topic to validation and shopper acceptance. This timeline suggests the pilot serves as a testing floor for technical refinement slightly than quick deployment.

The technical problem includes scaling passive measurement throughout Nielsen’s panel whereas sustaining statistical validity. Wearable units should obtain ample adoption amongst panelists to supply consultant samples throughout demographic segments. Machine compliance and knowledge high quality grow to be crucial components in figuring out whether or not co-viewing changes precisely replicate precise viewing habits or introduce new measurement biases.
Privateness issues accompany any wearable measurement know-how. Nielsen should guarantee audio seize mechanisms adjust to consent necessities and knowledge safety rules whereas sustaining panelist belief. The passive nature of wearable measurement raises completely different privateness questions than conventional distant control-based check-ins, requiring cautious implementation to steadiness measurement high quality with privateness safety.
The Tremendous Bowl represents a super testing floor for co-viewing measurement given the occasion’s recognized tendency to generate group viewing. Advertisers buying Tremendous Bowl stock particularly worth the occasion’s skill to combination mass audiences in shared viewing contexts. Correct co-viewing measurement may considerably improve reported viewership figures, doubtlessly justifying the premium pricing that Tremendous Bowl promoting instructions.
