If you really want to understand the influence streamers now command over Nielsen decision-making, consider this: After delaying a recalibrated version of its monthly Gauge report from this week to next to let it get its act together, Nielsen late today confirmed it will actually delay it until September.

"Well, the streamers whined and Nielsen caved," Fox Sports analytics exec Mike Mulvihill posted on X, after word got out of Nielsen's latest delay tactic.

In his post, Mulvihill attributed the decision to streamer reaction to a Wall Street Journal story reporting that streamers would have flipped places with broadcast/cable share.

Citing unnamed sources, the WSJ reported that the delayed February Gauge (covering January data) would have reported a 41.9% total day TV usage share for streaming vs. a 47.4% combined broadcast and cable share, almost exactly the opposite of what Nielsen's January Gauge (covering December 2025 data) reported for the two viewing sources.

"We will not be making any methodological changes for The February Gauge and will be releasing it in April with the same methodology that we used for January," Nielsen Chief Client Officer Peter Naylor told Variety in an article published late Friday.

All this, while Nielsen continues to struggle to implement multiple sets of adjustments -- not just the integration of new universe estimates (via the Advertising Research Foundation's DASH service) that would have been the basis for recalibrating The Gauge's share estimates, but complex mathematical models designed to make its Big Data + panel sample more representative of actual viewing.

Those adjustments are necessary to providing the "impact data" that will be necessary for buyers and sellers to calculate their share estimates to negotiate upfront deals based on what numbers Nielsen will be reporting in September.
