TVNewser is reporting tonight that legendary CBS newsman Walter Cronkite is "gravely ill," so ill that the network has been "updating his obituary."

The 92 year-old Cronkite, whose signature sign-off, "And that's the way it is," rang through the living rooms of millions of American homes on a nightly basis from 1962 to 1981, grew up in Missouri and Texas before dropping out of college to take a job covering sports at a newspaper. He went on to work in radio and was eventually discovered by Edward R. Murrow, who brought him on at CBS.

Perhaps Cronkite's most memorable moment at CBS was his on-air reporting of the assassination of President Kennedy in 1963, a moment that perfectly encapsulated the unshakable gravitas that is sure to be his lasting legacy for years to come.
