It was Rush Limbaugh who kept AM radio alive. When he appeared at the National Association of Broadcasters (NAB) Convention to speak, he got a standing ovation just for entering the room. The AM station owners knew who to thank.

With Rush gone for 3 years, AM radio is finished. I haven't even turned on the radio since he died.

Yes, he singlehandedly resurrected AM, and it was a single point of failure when he died.
