My personal favorite? The Fugitive with David Jansen, ran from 1863 to 1967. The final episode “The Judgment” in 1967 was the most watched TV program ever until the final episode of MASH years later.
The Fugitive also had the best music track ever for a TV show:

The Fugitive, how can that be forgotten; we watched it every day for awhile on reruns. David Jansen was great in that role. A true classic.
Whoops! I meant 1963 to 1967.
