I'd set the dial to go back about 50 years or so: Great-looking cars, rock 'n' roll, decent TV shows & movies, no nanny-state laws about seat belts, crash helmets, and such like.....
On the technical side, equipment was still being built to decent standards, television was really just about getting going in a lot of places and gearing up for the development which would follow over the next decade or two. Must have been a great time to be involved with TV.
Everybody had decent telephones (no throwaway "Made in China" garbage) and there were still thousands of the good old electromechanical exchanges in service to work on and appreciate the engineering from the past few decades.
