Thomas Magnum is off the case. CBS has cancelled the Magnum PI TV series so it won’t be returning for a fifth year and the 2022-23 TV season. *Status update below.

An action-drama series, Magnum PI stars Jay Hernandez, Perdita Weeks, Zachary Knighton, Stephen Hill, Tim Kang, and Amy Hill. Recurring performers include Lance Kim, Chantal Thuy, and Martin Martinez. This reboot of the 1980s TV show follows Thomas Magnum (Hernandez), a decorated former Navy SEAL who repurposes his military skills to become a private investigator. He lives in a guest cottage on Robin’s Nest, the luxurious estate where he works as a security consultant to supplement his P.I. business. The “majordomo” of the property is Juliet Higgins (Weeks), a beautiful and commanding disavowed MI:6 agent who keeps Magnum in line. When Magnum needs back-up on a job, he turns to his trusted buddies and fellow POW survivors, chopper pilot Theodore “TC” Calvin (Hill) and Orville “Rick” Wright (Knighton), a former Marine door-gunner who now runs a nightclub. Magnum frequently has run-ins with police detective Gordon Katsumoto (Kang) and the two are more alike than either cares to admit. The unofficial “House Mom” and cultural curator of Robin’s Nest, Teuila “Kumu” Tuileta (Hill) is also one of Magnum’s biggest fans.

Airing on Friday nights, the fourth season of Magnum PI averaged a 0.42 rating in the 18-49 demographic and 5.24 million viewers. Compared to season three, that’s down by 20% in the demo and down by 6% in viewership in the live+same day ratings (including DVR playback through 3:00 AM). In the live+7 day ratings, the reboot averaged a 0.70 demo and 7.38 million with delayed viewing added in. It is likely the most-watched broadcast series to be cancelled this season.

Deadline reports that the cancellation comes after CBS and the show’s studio, Universal Television, couldn’t come to an agreement for a fifth year. As traditional viewing has been dropping, networks are less willing to spend as much on shows that they don’t own. There’s no word yet on the potential of Universal TV shopping the series elsewhere.

In the past 24 hours, CBS has also cancelled B Positive, How We Roll, Good Sam, and United States of Al.

What do you think? Have you been keeping up with the Magnum PI TV series on CBS? Are you sorry to hear that it’s been cancelled and won’t have a fifth season?

*7/1/22 update: NBC has made a deal to revive the Magnum PI series for seasons five and six.
