Caitlin Clark is at the center of a ratings debate after two networks issued competing “most-watched” claims for Indiana Fever games in July.
CBS said its July 18 Fever vs. New York Liberty broadcast averaged 2.579 million viewers and peaked at just over 3 million. NBC reported its July 12 Fever vs. Las Vegas Aces telecast averaged a Total Audience Delivery of 2.64 million across NBC and Peacock, peaking near 2.8 million.
Side-by-side numbers: what each network reported
Both networks promoted headline audiences, but they used different measurement definitions and collection methods.
| Game (date) | Average audience | Peak | Measurement |
|---|---|---|---|
| Fever vs. Liberty (July 18) | 2.579 million | Just over 3 million | Nielsen Big Data + Panel (television-focused) |
| Fever vs. Aces (July 12) | 2.64 million (Total Audience Delivery) | About 2.8 million | Nielsen TV + Adobe Analytics streaming (combined) |
Short stat graphic: the NBC combined figure (2.64M) is roughly 2.4% higher than CBS’s Nielsen TV figure (2.579M).
How measurement methods change the picture
Plain language: these metrics count different viewers. Nielsen’s Big Data + Panel primarily measures television sets and linear distribution. NBC’s Total Audience Delivery blends Nielsen’s TV numbers with Adobe Analytics streaming counts from Peacock, producing a combined broadcast+streaming reach.
Because NBC’s total includes digital streaming that CBS’s Nielsen TV figure does not, the two headline numbers are not apples-to-apples and should not be treated as direct equivalents.
Independent trackers help break the totals apart: Sports Media Watch reported NBC’s linear-only audience at about 2.46 million, implying the remaining roughly 180,000 in NBC’s 2.64 million came from streaming counted via Adobe Analytics.
Caitlin Clark and Indiana: why they matter to these ratings
The Indiana Fever have produced multiple very large national TV audiences this season. Caitlin Clark’s presence coincided with those spikes and likely contributed to elevated viewership, but measurement choices, scheduling and opponent-level interest also shape the reported totals.
Clark-linked games produced two audiences above 2.5 million within a six-day span on different networks and against different opponents — an unusual cluster for regular-season WNBA telecasts.
For context, the only regular-season WNBA game since 2000 to draw a larger audience than these recent games was the Fever’s 2025 opener on ABC, which averaged 2.7 million and peaked above 3 million.
Historically, Indiana has appeared in the 28 highest-rated WNBA regular-season games of the past 20 years, a fact that reflects both market interest and repeated national exposure.
By the numbers: clear takeaways
- NBC’s Total Audience Delivery (2.64M) exceeded CBS’s Nielsen-measured TV audience (2.579M) by about 61,000 viewers — roughly 2.4%.
- Sports Media Watch’s linear-only estimate for the NBC telecast was ~2.46M, indicating about 180,000 viewers in NBC’s total came from streaming measurement.
- CBS’s 2.579M is the largest single-network Nielsen Big Data + Panel audience reported this season for a WNBA regular-season game.
- Neither network is definitively “wrong” in promotional terms: each used an industry-accepted metric that favors its distribution method (television-only vs. combined broadcast+streaming).
What comes next
Expect more mixed claims as networks fold streaming figures into promotional totals. Readers should look for explicit labeling — television-only, streaming-only, or combined — whenever a record or “most-watched” line is promoted.
Outlets such as Sports Media Watch that publish linear-only and combined tallies side-by-side make it easier to compare components behind headline claims.
FAQ
Which game had the higher reported audience?
NBC’s combined Total Audience Delivery for the July 12 Fever-Aces game was reported at 2.64 million, higher than CBS’s Nielsen-reported 2.579 million for the July 18 Fever-Liberty game. That comparison mixes different measurement types.
Why do CBS and NBC report different viewership totals?
CBS cited a Nielsen Big Data + Panel television figure. NBC reported Total Audience Delivery, which adds Peacock streaming (measured with Adobe Analytics) to Nielsen’s TV numbers. Different inclusion rules produce different headline totals.
Did Caitlin Clark cause the ratings increase?
Caitlin Clark’s presence coincided with several of the season’s biggest audiences and is a central element in those spikes, but the headline totals also reflect how networks count viewers, scheduling, and opponent interest. Measurement method matters when interpreting cause and scale.
