The new rules of the game

Companies are innovating to move from the sidelines to the center of competition. Take soccer balls, for instance. Inside a recent version, a motion sensor captures the ball's movement hundreds of times per second, transmitting real-time data to match officials to support offside decisions and other reviews. Combined with semi-automated offside technology and player tracking, the connected ball can detect touches that would be nearly impossible for the human eye to catch.

When a match can hinge on an almost imperceptible touch detected by a sensor, technology isn't simply assisting referees, it may be  changing the outcome of a game, so this new technology could create heated debate.

But soccer isn't the only sport embracing a digital assist.

After years of testing in the minor leagues, Major League Baseball introduced its Automated Ball-Strike Challenge System, powered by T-Mobile, during spring training last year and used it in the 2025 All-Star Game, allowing players and coaches to initiate reviews of close pitches. Rather than replacing home plate umpires outright, the technology, which monitors the exact location of each pitch relative to the specific batter’s zone, acts as a second opinion, preserving the human element of a historic game while increasing confidence in critical calls. It's a model that recognizes technology doesn't always have to replace people; sometimes its greatest value comes from supporting better decisions. MLB formally debuted the system with the 2026 season and it will be in action next week at the 2026 All-Star Game, presented by Mastercard.

Tennis has gone even further.

At several major tournaments, electronic line calling has replaced line judges entirely, with the Hawk-Eye camera system (also used in the MLB Challenge System) determining whether a ball lands in or out within fractions of a second. For many players, the system has reduced disputes and improved consistency. For others, it has marked the end of one of sport’s most recognizable traditions. Accuracy has improved, but so too has the debate about what is gained and lost when technology replaces human judgment.

Taken together, these innovations reveal a bigger trend. Technology is becoming woven into nearly every part of sports, from the equipment athletes use to the officials making the calls. Sensors, cameras and real-time analytics are making decisions faster and more precise than ever before.

For fans, there are obvious upsides. Faster reviews keep games moving, more accurate calls build confidence in the outcome and richer data helps explain pivotal moments in new ways. But sports have never been only about precision. The controversial call, the heated debate and the human element have always been part of what makes competition memorable.
