Sports have always revolved around the main event. The opening whistle, the game-winning drive, the buzzer beater. Yet for today’s fans, the real action lives in the 21 hours surrounding the game, not just the time spent on the field. That is when fans are on their phones, in their feeds, tinkering with fantasy lineups and scrolling through an endless stream of highlights, memes and breaking news. For many the concept of sports advertising is centered around the highly engaging, but also notoriously expensive TV commercials during the game. Live slots are far less effective than spreading that spend to meet the fan across their journey pre-, during, and post-game.

Teams, leagues and sponsors have the most to gain in the action off the field. While innovative properties are aware of the opportunity, it remains largely untapped due to the technical complexity of digital media, the investment required to buy efficiently, and the opaque ad tech landscape. 

The 21 Hours Where Fandom Lives

The traditional model of sports marketing still revolves around game time. Tickets sold, seats filled, commercials, the signage and intellectual property inside the venue. Most fans’ relationship with their favorite team is mediated almost entirely through third-party environments that sit outside the control of the rights holder’s ecosystem. According to research from S&P Global, over two-thirds (68%) of US sports fans indicated they watch live sports on TV or through an online streaming service and only one-quarter (25%) indicated they attend sporting events in person.

Take the NFL for example. They are by far the most popular U.S. professional sports league with the most passionate fans, but each team only has eight home games. When you remove season ticket holders, your in-stadium audience is much smaller than anticipated. Even so, the live audience pails in comparison to the engaged fanbase beyond the stadium.

In the 21 hours around the game, a typical fan might watch pregame shows, scroll through social commentary, read analysis from beat writers and creators, check fantasy lineups or player props, and compare jerseys or collectibles from multiple sellers. To the fan, this feels like one continuous, emotion driven journey. To most organizations, it still looks like a fragmented mix of third party media platforms. 

That gap is the blind spot. It is where the relationship is formed and where fans move down the funnel from awareness to consideration to conversion. 

Displaced and Player-First Fans: The Next Generation of Super Fans

This challenge grows bigger when you look at how fandom itself has changed. A large share of fans are now displaced. They do not live in the home market of the team they support. A fan could be multi-generational, whose family has been following a club for years. Or they follow their childhood club from another state or stick with the team they fell in love with while working or studying abroad. 

Increasingly, fans have become loyal to players first and teams second. One draft pick or blockbuster trade does more than reshape a roster. It quietly unlocks entirely new fan bases. College alumni who have followed that player for years. Fans of the player’s previous team. Regional pockets of supporters half a country or half a world away. Think Shohei Ohtani, Victor Wembanyama, or Caitlin Clark! These fans are deeply engaged, but rarely in the building - and may not care much about the outcome of a game or a team’s performance. 

Fans watch highlights on mobile, debate trades in group chats, check stats in fantasy apps and refresh betting lines. For some, their primary interest is not the sport at all, it’s the cultural impact of a player, a moment, a championship run. This collection of fans sit across the open web, not inside a stadium. If partners approach fans through the traditional lens (e.g. local markets, broadcasts, and in-venue activations), it leaves displaced and player-first fans underserved. Not only are they a larger audience than those in the venue, but they’re truly addressable across the open web. 

Second-screen environments are the bridge from proximity to performance. They can align partner messaging with the specific stories fans are consuming in real time and turn vague concepts like “brand lift” into tangible signals. Clicks, searches, content engagement and conversions become part of the sponsorship narrative and more importantly, the fan experience.

Teams and Leagues as Emerging Media Networks

If rights holders connect those dots, they move beyond selling sponsorships and begin to operate something closer to a sports-focused retail media network. Access to a high-intent, national fan base becomes a product in its own right. Brands gain more measurable ways to reach fans based on the stories and contexts they care about. Teams and leagues demonstrate real performance against brand and business goals. Fans receive experiences that feel additive and relevant, not generic or intrusive.

The future of growth for rights holders and sponsors will be decided in the 21 hours around the game on screens that fit in the palm of a fan’s hand. The organizations that treat that window as their primary canvas will define what modern sports sponsorship and advertising looks like.
