I don't remember a night when me, Mom and Dad weren't sitting around the Dinner Table, and he wasn't on the screen, followed shortly thereafter by Walter Cronkite and Dan Rather. And of course, for most of those years, he was paired by Maureen Bunyah...
Of course, that was WUSA (formerly WTOP) Channel 9, the DC CBS Affiliate. Now, they're on Channel 7, the ABC affiliate, because WUSA (run by Gannett) are cheap bastards.
