Detroit Radio: Jim O'Brien Exits Beasley's WCSX FM

Longtime morning radio host Jim O'Brien, known as "Big Jim," has ended his run at classic rock station 94.7 WCSX-FM, closing the popular "Big Jim's House" show after more than two decades on air.

O'Brien announced his departure Thursday, May 14, 2026, via social media, stating: "After an incredible run at WCSX, my time with the station has come to an end. I'm grateful to the listeners, teammates, clients, veterans, and Detroit community who allowed me to be part of their mornings for so many years. Detroit has been my home for 24 years, and I'm proud of everything we built together. More to come soon."

The show, which aired weekdays from 6 a.m. to 10 a.m. and featured co-host Jenny Jenny in recent years, was a staple of Detroit's morning radio lineup, blending rock music, local banter, community engagement, and O'Brien's signature personality.

O'Brien joined WCSX in 2002 and became one of the market's most recognizable voices. A U.S. Navy veteran who served eight years in the submarine service, he was deeply involved in local causes, raising millions for charities and supporting veterans' initiatives across southeast Michigan. He also contributed to naming local honors like Glenn Frey Drive and Bob Seger Boulevard.

The exit appears to be part of broader cost-cutting measures at owner Beasley Media Group, which has seen other veteran departures recently.

Despite leaving the station, O'Brien emphasized he is "not going anywhere" and expressed excitement for future opportunities. No immediate replacement for the morning slot has been announced by WCSX.
