Live sports is the last reliable mass audience in media, and that audience is far more multicultural than most of the marketing built around it. Nielsen's data makes the gap impossible to ignore, and it points straight at where the next decade of fandom is going to be won.
Who's actually watching
In its 2025 Tops of Sports report, Nielsen found that the NBA postseason has the highest concentration of Black and Asian viewers of any major U.S. sport, audiences Nielsen explicitly calls “critical growth audiences for brands.” These aren't fringe viewers; they're the leading edge of where sports audiences are heading.

AANHPI viewership spike Shohei Ohtani drove (2025 MLB Tokyo Series)
One player can move an entire audience
Representation isn't a soft value in sports, it's a measurable lever on viewership. Nielsen credited Shohei Ohtani with a 113% spike in AANHPI viewership during the 2025 MLB Tokyo Series. When a community sees itself on the field, it shows up to watch. And the appetite is well ahead of the supply: a majority of AAPI audiences say they wish they saw more representation on TV.
The crowd already changed. The marketing hasn't caught up.
Why brands keep missing it
The data is clear; the execution usually isn't. Most brands still treat multicultural fans as a niche to bolt onto a general-market plan. A logo on a jersey isn't engagement. A translated tagline isn't cultural fluency. And a one-off heritage-month activation isn't a relationship. Fans can tell the difference between a brand that shows up in their community and one that's just renting space near it.
What it takes to win these audiences
- Cultural fluency, not translation. Know the difference between showing up in a community and being claimed by it, that's the whole game.
- Built for, not adapted to. Design the work for the audience from the start, on the platforms culture actually lives on.
- Beyond game day. Community and experiential programs turn audiences into loyalty that deepens between seasons, not just during them.
- Measured by what moves. Engagement, loyalty, and growth, not impressions a media plan can manufacture.
The teams, leagues, and brands that read Nielsen's numbers as a signal, and build for the audience that's actually in the stands, are the ones who'll own the next decade of fandom. The rest will keep marketing to a crowd that left a while ago.
