Nielsen published the second-quarter 2026 edition of its Ad Supported Gauge on August 25, 2026 from New York, reporting that advertising-funded platforms accounted for 71.5% of all United States television viewing, a 1.3 share point decline from the first quarter, with streaming taking 48.2% of the category and cable holding at 25.2%.

The quarterly report is the narrower sibling of Nielsen's monthly Gauge. Where the monthly report divides all television time between broadcast, cable, streaming and residual set usage, the Ad Supported Gauge first separates viewing that carries advertising from viewing that does not, then splits the advertising-funded portion three ways. For buyers, the second calculation is the one that describes addressable supply rather than attention in general.

What the second quarter produced

Ad-supported platforms captured 71.5% of total viewing between April and June 2026. That figure sits 1.3 share points below the first quarter of the same year, which places the first-quarter reading at 72.8%.

Within the advertising-funded portion, streaming reached 48.2%, an increase of 1.6 share points on the previous quarter. Cable finished at 25.2%, the same level it recorded in the first quarter. Broadcast closed at 26.6%.

According to Nielsen, broadcast viewing followed its typical seasonal decline from the first quarter to the second, though the drop was softer than in the equivalent period a year earlier. The company attributes that softening to sports programming, naming the NBA playoffs and early World Cup coverage specifically. Measured against the second quarter of 2025, broadcast gained 0.6 share points, rising to 26.6% from 26.0%.

The arithmetic underneath the headline

Three category shares must total 100%. Cable did not move. Streaming added 1.6 points. Broadcast therefore gave up 1.6 points inside the quarter, falling from an implied 28.2% in the first quarter of 2026 to 26.6% in the second.

That is the tension the release carries without resolving. Nielsen's own framing credits live sport with bolstering broadcast, and on a year-over-year basis the claim holds: 26.6% against 26.0% twelve months earlier. On a quarter-over-quarter basis, broadcast was the only category to lose ground, and every point streaming gained came from it. Both readings are drawn from the same table. Which one a seller quotes in a deck depends on which comparison window serves the argument.

The longer series adds a third angle. Nielsen's 2026 Upfront Planning Guide, published in March, put ad-supported viewing at 74.2% of total television in the fourth quarter of 2025, described at the time as the highest point across all four quarters of that year. From that peak, the category has fallen in two consecutive quarters: to 72.8%, then to 71.5%. The composition of ad-supported television is shifting toward streaming, while the size of ad-supported television relative to everything else on the set is contracting.

The age cut reverses the ordering

The most consequential table in the release is the demographic one, and it does not appear in the headline.

Nielsen ran the same split for Adults 18 and older rather than Persons 2 and older. Moving to that base reallocates 3.8 share points away from streaming, dropping it to 44.4%. Broadcast rises to 28.6%, a gain of 2.0 points. Cable rises to 27.0%, a gain of 1.8 points.

The gap between the two views is 3.8 points on a single variable. Under the total-viewing base, streaming leads broadcast by 21.6 points. Under the adult base, the lead narrows to 15.8 points, and cable moves to within 1.6 points of broadcast. Nothing about actual viewing changed between the two rows. Only the population definition did.

That distinction has a direct bearing on planning. A campaign guaranteed against adults does not buy the Persons 2+ distribution, yet the Persons 2+ distribution is the number that circulates in presentations and trade coverage. Children and teenagers concentrate in streaming, and their inclusion pulls the aggregate toward it.

Sport as the swing factor

The two properties Nielsen names, the NBA playoffs and the opening phase of the World Cup, both sat largely on linear rights during the measurement window.

Nielsen's Spring 2026 Tops of Sports report had already documented the basketball trend, recording a 27% increase in average NBA regular-season audience and a further 10% lift in the early playoff rounds. The Finals themselves ran in June as a five-game series, with ABC carrying the domestic broadcast and Amazon distributing the same series across seventeen named international markets on Prime Video.

The tournament arrived in the final three weeks of the quarter. The Video Advertising Bureau had projected that 63.9 million United States adults would watch, or 24% of the adult population. FOX held English-language rights to 68 of the 104 matches, with Telemundo carrying Spanish-language coverage.

Nielsen's monthly Gauge for June, published on August 18, 2026, recorded broadcast at 19.8% of total television against cable's 19.5%, the first June share increase broadcast had posted since the Gauge began in 2021, on a 118% month-over-month rise in broadcast sports viewing. Cable sports viewing fell 10% in the same interval as the NBA and NHL playoffs concluded. The quarterly Ad Supported Gauge blends April, May and June, which compresses that late swing into a single figure and removes the sequence from view.

There is a further boundary worth noting. The World Cup ran from June 11 to the July 19 final. The second quarter closes on June 30. The knockout rounds, including the match that drew a preliminary 24.4 million viewers on the FOX Television Network, fall into the third quarter and outside these numbers entirely. iSpot counted more than 25 billion television advertising impressions across FOX, FS1, Telemundo and Universo for the tournament as a whole.

Cable's flat line

Cable holding at exactly 25.2% across two quarters is the least dramatic figure in the release and, for sellers, one of the more useful. It indicates that the category's ad-supported share stopped eroding for a six-month stretch, at least on this measurement basis, even as the monthly Gauge showed cable's share of all television slipping from 20.4% in May to 19.5% in June.

The two readings are not contradictory. One measures cable against every other use of the television set; the other measures it against the two other advertising-funded categories. A category can hold its position among advertising-funded platforms while the advertising-funded bloc as a whole loses ground.

Underneath the flat line, distribution continues to consolidate. Fubo and Disney's Hulu + Live TV completed a merger in October 2025 that produced a vMVPD with close to 6 million North American subscribers, the sixth-largest pay television operation in the country. Fubo's most recent quarterly results showed advertising revenue of $108.9 million in the World Cup quarter.

What sits inside the streaming bucket

Nielsen reports streaming as a single ad-supported category, which conceals a mix of business models with different inventory characteristics. Ad tiers on subscription services, FAST channels distributed through aggregators, and advertising-supported video on demand all resolve to the same 48.2%.

The commercial performance inside that bucket has been uneven. Comcast reported that Peacock reached its first profitable quarter at $189 million of adjusted EBITDA in the second quarter of 2026, on domestic Media segment advertising revenue of $2.16 billion, up 55%. Advertising revenue per Peacock subscriber rose 43% to $4.98 a month. Comcast attributed the quarter to the simultaneous presence of the World Cup, the NBA playoffs and Love Island USA, and stated that none of the three recurs in the same form in the third quarter.

Scale on the audience side has been documented separately. Video Advertising Bureau research published in April 2026 put ad-supported streaming reach at 209.4 million United States viewers, with connected television advertising projected at 43% of total television ad spend in 2026.

The methodology note attached to the release

Nielsen appended a caveat to the Q2 2026 edition. According to the company, the published version of the Ad Supported Gauge has not migrated to the Advertising Research Foundation DASH-based media related universe estimates, a migration planned for the autumn. Nielsen states that this matters because the current approach, while consistent with previous months of the Gauge, will produce different results than production data.

That sentence connects the report to a dispute that has run through 2026. In March, the Video Advertising Bureau accused Nielsen of suppressing a February Gauge edition that would have shown linear television at 47.4% of viewing time against streaming's 41.9%. Analysts subsequently framed the argument as a contest over which side of the linear and streaming divide captures budget rather than a technical disagreement. Netflix co-chief executive Greg Peters addressed the pending change on the company's April 16 earnings call, characterising it as a change in Nielsen's numbers rather than in viewing behaviour.

Universe estimates set the denominator against which every share is calculated. A revision to them moves reported figures without any change in what households watched. The autumn migration therefore means that the 71.5% published on August 25 is not directly comparable with whatever the Ad Supported Gauge reports for the fourth quarter of 2026.

A second, separate track reaches its deadline within days. Nielsen confirmed on August 19 that seven enhancements to its Big Data + Panel currency take effect on August 31, 2026, covering co-viewing capture through wrist-worn wearables, a latency-adjusted DASH universe estimate, a household demographic assignment model, integrated weighting, Hispanic universe estimation, an ACR monitored tuning adjustment and householding for one big data provider. The seven items had first been documented publicly by the Video Advertising Bureau on July 14. Nielsen paired the confirmation with a statement that no ratings increase is guaranteed.

Neither the Gauge nor the Ad Supported Gauge is Nielsen's currency dataset. The currency ratings that settle advertising contracts sit in a separate system, and Nielsen has said so directly in recent Gauge releases. The two nevertheless move in the same methodological weather, and the Ad Supported Gauge migrates to the same ARF inputs in the autumn.

Publication lag

The Q2 2026 Ad Supported Gauge landed on August 25, roughly eight weeks after the quarter closed. The monthly reports have drifted on a similar trajectory. Nielsen released the June 2025 Gauge on July 15, 2025, a lag of about two weeks. The May 2026 edition appeared on July 28, 2026, and the June 2026 edition on August 18.

For planners reading the market in motion, a report describing April through June and arriving in late August functions as history rather than signal. The upfront negotiations it might have informed largely closed in the intervening period.

Why this matters for the marketing community

Three practical points fall out of the release.

First, the share ordering depends on the population base, and the release publishes both. Under Persons 2+, streaming leads broadcast by 21.6 points. Under Adults 18+, the lead compresses to 15.8 points and cable sits within 1.6 points of broadcast. Guarantees are written against demographics, not against total persons, which means the adult table describes the traded market more closely than the headline one.

Second, the shrinking denominator is a separate story from the internal split. Ad-supported television has moved from 74.2% of total viewing in the fourth quarter of 2025 to 71.5% in the second quarter of 2026. Streaming winning a larger portion of a contracting bloc is not the same as advertising-funded inventory growing. The two trends have been reported together and read as one.

Third, the comparison window is doing argumentative work. Broadcast is up 0.6 points year over year and down 1.6 points quarter over quarter within the ad-supported category. Sellers on both sides of the linear and streaming divide can source a favourable number from this single release without misquoting it.

Nielsen's own commercial position has moved during the same period. The company agreed on August 6, 2026 to acquire DoubleVerify for approximately $2.15 billion in an all-cash transaction, folding advertising verification into the corporate structure that sets television audience currency. That combination has raised questions about independent scrutiny of both functions.
