As for where the "black" or "billiard" spot ended up on the snooker (billiards) table.... In the early days of English billiards (1800s and early 1900s), a standard shot was to pocket the red ball off the billiard (now, black) spot which was worth 3 points and then the red would respot on its spot. The highest number of consecutive "winning hazards" (pocketing the red ball) or "spot strokes" (pocketing the red from its spot) was something over 600 shots. In order to make such play harder the spot was moved around and the pocket sizes were changed.
Here is some info from the amazing book "Billiards" by Major William Broadfoot, 1896. It is a book that anyone who is interested in the history of billiards should have.
