In the past, and I am not "that" old, I voted on paper ballot - with a pencil. After polls were closed, the locked ballot box was then driven to the county seat, some 30 miles away, and counted. We knew the winner of elections by the 11 o'clock news.
Many years ago I was in Canada attending a conference on their election day. In the evening they had the results reported from the entire country in a matter of hours—and they have 6 time zones. (Newfoundland is half an hour ahead of the Atlantic time zone.)
