There’s a reason Tracker is TV’s biggest show — and it all has to do with leading man Justin Hartley.
Before introducing Us to Colter Shaw, Hartley got his start on soap operas, including Passions and Young and the Restless. He then moved on to Smallville, Revenge and Mistresses ahead of his fan-favorite role as Kevin Pearson on NBC’s This Is Us. Hartley walked away from the hit series with three nominations for the Critics’ Choice Television Awards and ultimately branched out with movie roles in A Bad Moms Christmas, Senior Year, The Noel Diary and more.
But it was Hartley’s passion project — Tracker — that proved that the actor knows what TV fans want. The show, which premiered in February 2024, quickly found success after being coined the most-watched broadcast premiere since NCIS‘ final episode with Mark Harmon in September 2021. Its average viewership was reported to be 18.2 million per episode, according to Paramount+ and broadcast measurements.
Variety‘s annual list of the year’s 100 most-watched primetime telecasts revealed that Tracker episodes earned 15 top spots. Despite making Us wait 11 weeks for new episodes, the second season dominated viewership with the season 2 premiere bringing in 8.3 million total viewers — a nearly 10 percent increase in viewership from the season 1 finale. The season 2 premiere also marked the show’s highest audience since the series debuted in February 2024 after the Super Bowl.
At the center of the series is Hartley’s Colter, who welcomes the audience week to week while solving various missing cases across the country.
“I think we’ve crafted a character that is so emotionally evolved, and he really does want to get to the root of why people do things,” Hartley continued. “The facts are that [executive producer] Ken Olin and I set out to do a show that was in fact a throwback. We wanted a new spin on a procedural, meaning our character would evolve over time.”
Hartley added: “He would not just remain the same exact person every single week. We were hopeful people would like it. People ended up loving it. I think there’s a huge appetite for this kind of show.”

Ready for His Close-Up
While not necessarily a scene from the show, CBS has gotten creative with its themed photo shoots for each season of the show. Our personal favorite has to be Hartley hanging out in an Airstream while channeling his inner Colter.
