When I was growing up in single-channel television land an absolute "must see" every week was Hawaii Five-O, which aired from September 1968 to April 1980. The theme music is well known and the introductory sequence would not be out of place in today's special effects CGI enhanced television and film. Here is the opening sequence via YouTube which I came across today (while of all things I was looking for a graphic of a Google Android phone!):
Jack Lord (as Steve McGarrett) was the coolest guy on the planet. Each episode built up to the inevitable climax where McGarrett would say "Book 'em Danno" - the Five-O team always got their man. Classic television - one of my favourites of all time.
