How Has Volleyball Changed Over The Years?

Back then..... :)

1.The net was 6 feet, 6 inches high.
2. The court was 25 X 50 feet
3. Any number of participants was allowed.
4. The length of the game was nine innings, with three outs allowed per team per inning.
5. Continuous air dribbling of the ball was permissible up to a restraining line 4 feet from the net.
6. No limit on the number of hits on each side of the court.
7. A served ball could be assisted across the net.
8. A second serve (as in tennis) was permitted if the first resulted in a fault.
9. Any ball hitting the net, except on the first service, was a fault and resulted in side out.
