The announcement was made by his wife on the radio show.

Rush Limbaugh, the icon who transformed political talk radio, has died following a battle with lung cancer. He was 70.

Limbaugh's wife, Kathryn, announced the news on his radio show on Wednesday morning.

He revealed he'd been diagnosed with Stage IV lung cancer during his last radio broadcast of 2020, saying, "I wasn't expected to be alive today. I wasn't expected to make it to October, and then to November, and then to December. And yet, here I am, and today, got some problems, but I'm feeling pretty good today."

The Rush Limbaugh Show began in 1988, and Limbaugh spent over 30 years behind the microphone. When the show first started, it was only on 56 radio stations. It has since grown to be aired on more than 600 stations across the nation, with an average of 27 million listeners tuning in on a weekly basis.

Limbaugh is survived by his wife, Kathryn.
