TV shows usually run for several seasons (might also be one), then finished, with the production company officially declaring there won't be more seasons. Fair enough.
However, I wonder if there were any TV shows that "returned from the grave", i.e. got back to another full season after being officially finished?
Not talking about "reunion chapter" which is probably common, or about TV shows aborted mid-season then bought shortly after by different producer, but about TV shows which had at least one full season, finished "gracefully", then came back after a while for whole new season.
Yes, I know Friends almost made it last year (that's what inspired the question. :))
