Here's Cronkite's famous clip announcing the assassination of JFK:
Cronkite was the broadcaster to whom the title "anchorman" was first applied, and he came so identified in that role that eventually his own name became the term for the job in other languages (Swedish anchors are known as Kronkiters; in Holland, they are Cronkiters).
"He was a great broadcaster and a gentleman whose experience, honesty, professionalism and style defined the role of anchor and commentator," CBS Corp. chief executive Leslie Moonves said in a statement.
His 1968 editorial declaring the United States was "mired in stalemate" in Vietnam was seen by some as a turning point in U.S. opinion of the war. He also helped broker the 1977 invitation that took Egyptian President Anwar Sadat to Jerusalem, the breakthrough to Egypt's peace treaty with Israel.
He followed the 1960s space race with open fascination, anchoring marathon broadcasts of major flights from the first suborbital shot to the first moon landing, exclaiming, "Look at those pictures, wow!" as Neil Armstrong stepped on the moon's surface in 1969. In 1998, for CNN, he went back to Cape Canaveral to cover John Glenn's return to space after 36 years.
