Very sad. I grew up with Mike on the teevee and here recently wondered what he really thought of Chris.

Mike Wallace, a pioneer of American broadcasting who confronted leaders and liars for the newsmagazine “60 Minutes” for four decades, has died, CBS News said Sundaa morning. He was 93.

His death was announced on CBS by the anchor of its Sunday morning program, Charles Osgood. The network did not immediately specify when or where he died. Mr. Wallace had been ill for several years.

As one of the original correspondents and hosts of “60 Minutes,” which was started in 1968, Mr. Wallace helped to establish the television newsmagazine format. “60 Minutes” is now the most popular such program on American television.

Mr. Wallace was perhaps best known for ambush interviews of crooks and cheats. Mr. Wallace “invented a new paradigm for television news, creating a signature technique that would become a standard in the industry,” the biographer Peter Rader writes in a new book, “Mike Wallace: A Life.”
