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.
And his style never was all about surprise, anyway. Wallace was a master of the skeptical follow-up question, coaxing his prey with a "forgive me, but ..." or a simple, "come on." He was known as one who did his homework, spending hours preparing for interviews, and alongside the exposes, "60 Minutes" featured insightful talks with celebrities and world leaders.
He was equally tough on public and private behavior. In 1973, with the Watergate scandal growing, he sat with top Nixon aide John Ehrlichman and read a long list of alleged crimes, from money laundering to obstructing justice. "All of this, Wallace noted, "by the law and order administration of Richard Nixon."
The surly Ehrlichman could only respond: "Is there a question in there somewhere?"
