Despite airing on Friday nights, Magnum PI has remained a solid performer for CBS in the ratings. Will this trend continue and be enough to keep the series on the air? Will Magnum PI be cancelled or renewed for season five? Stay tuned.

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.

The ratings are typically the best indication of a show’s chances of staying on the air. The higher the ratings, the better the chances for survival. This chart will be updated as new ratings data becomes available.

For comparisons: Season three of Magnum PI on CBS averaged a 0.52 rating in the 18-49 demographic and 5.59 million viewers.

Note: These are the final national ratings, including all live+same day viewing and DVR playback (through 3:00 AM). Early fast affiliate ratings (estimates) are indicated with an “*”. While these numbers don’t include further delayed or streaming viewing, they are a very good indicator of how a show is performing, especially when compared to others on the same channel. There can be other economic factors involved in a show’s fate, but typically the higher-rated series are renewed and the lower-rated ones are cancelled.

What do you think? Do you like the Magnum PI TV series on CBS? Should it be cancelled or renewed for a fifth season?
