CBS’s 3-Part Lone Wolf Howls to No. 1 as TV’s Most-Watched Show
In a landscape ruled by sitcoms and copy‑paste procedurals, CBS has a three-part rule-breaker that’s surged past the pack to become TV’s most-watched event. Proof that broadcasters still have fresh tricks beyond the first-responder, legal, police, and medical formulas.
Network TV still worships at the altar of the procedural, but every now and then someone breaks the template and runs away with the ratings. CBS has one of those unicorns right now: a one-man weekly mystery that somehow became TV's most-watched show.
Procedurals still rule, but this one refuses to play by the usual rules
Most of the broadcast leaderboard is the usual mix of first-responder, legal, police, and medical comfort food. Think NCIS. Think Chicago Med. Even a Yellowstone offshoot like Marshals is muscling in. Networks also keep trying to freshen the formula at the edges — Kathy Bates' Matlock reboot is a swing, and the gone-too-soon Found showed there is appetite for weirder, twistier approaches. But the safe bet is still big ensembles doing case-of-the-week with familiar vibes.
Tracker said: cool, but what if it was basically one guy?
Tracker, in short
Premiering in 2024, Justin Hartley plays Colter Shaw, a roaming expert at finding missing people who picks up jobs all over the map while quietly working through the mystery of his father's death. Most episodes drop him into a new town with new faces, and he teams up with locals as needed. No standing task force. No bullpen of regulars trading quips. It lives and dies with Hartley on the ground.
The numbers (and yeah, they are huge)
- Post–Super Bowl LVIII launch: 18.4 million viewers
- Season 1 weekly average: 10.4 million viewers
- Season 2 weekly average: 17.34 million viewers
Even with the normal slide after a Super Bowl boost, the show settled into monster territory and has mostly stayed there. For stretches of its run, nothing else on TV has really been in striking distance.
Why the single-lead setup works... and why it might crack
To be fair, Colter is not completely alone. He gets remote assists from lawyer Reenie and the ever-handy Randy, who usually pop in to feed him key info and then pop back out. Jensen Ackles shows up now and then as Colter's brother, Russell Shaw, but never for more than a couple of episodes per season. When you zoom out, Hartley is the only series regular. No Hartley, no show. It's a very un-network move — and a big reason people keep coming back is because the entire thing is built around watching him work.
But that also means the whole production rests on one person's shoulders, week after week, season after season. Network schedules are a grind, and Hartley is also a producer. If CBS wants Tracker to run for years, the storytelling probably needs to widen out — more recurring characters with actual arcs, fewer one-and-done helpers, and a support system that doesn't vanish the second Colter leaves town.
Season 4 is locked; now comes the hard part
Tracker has a fourth season confirmed, and it will be back in the 2026 –2027 cycle. So will Marshals, which has already started nipping at its heels. If Marshals builds, it has a real shot at taking the crown. That is the competitive pressure point for CBS: keep Tracker the juggernaut next year and make it durable enough to last beyond that.
Bottom line: the lone-wolf experiment paid off in a big way. To keep cashing those checks, Season 4 needs to evolve — not abandon what works, but give Colter a world that feels like it exists even when he isn't in the frame.
Where to watch
Tracker airs Sundays on CBS and streams on Paramount+. If you have thoughts on how the show should expand in Season 4, drop a comment — I want to hear your fixes.
