said its ailing chief executive, Lowry Mays, will be absent "for as much time as he needs" to recover from brain surgery.
The company named Mays' son Mark Mays as interim CEO, indicating it expected the senior Mays to return to the post. Mark Mays is currently the media company's president and chief operating officer.
"I have decided to take some time off to focus on my health, so that when I come back, I am at 100%," Lowry Mays was quoted saying in a statement. He was operated on for a blood clot on his brain. "While I am gone, I have complete confidence in Mark along with all of the managers at Clear Channel to keep things running smoothly."
The company disclosed the CEO's condition in a press release Tuesday that also trumpeted the company's first-quarter earnings rising 64% from a year ago, thanks to revenue gains in its three main business lines.
