In December 2007, Wallace landed the first interview with Clemens after the star pitcher was implicated in the report by former Sen. George Mitchell on performance enhancing drugs in baseball. The interview, in which Clemens maintained his innocence, was broadcast in early January 2008.
Wallace's "extraordinary contribution as a broadcaster is immeasurable and he has been a force within the television industry throughout its existence," Leslie Moonves, CBS Corp. president and CEO, said in a statement Sunday.
Wallace was the first man hired when late CBS news producer Don Hewitt put together the staff of "60 Minutes" at the TV news magazine's inception in 1968. The show wasn't a hit at first, but it worked its way up to the top 10 in the 1977-78 season and remained there, season after season, with Wallace as one of its mainstays. Among other things, it proved there could be big profits in TV journalism.
The top 10 streak was broken in 2001, in part due to the onset of huge-drawing rated reality shows. But "60 Minutes" remained in the top 25 in recent years, ranking 15th in viewers in the 2010-11 season.
The show pioneered the use of "ambush interviews," with reporter and camera crew corralling alleged wrongdoers in parking lots, hallways, wherever a comment – or at least a stricken expression – might be harvested from someone dodging the reporters' phone calls.
Such tactics were phased out over time – Wallace said they provided drama but not much good information.
