The FIVB has just launched a new youtube channel aimed to showcase the history of the sport. The first video they have uploaded is a clip from the 1964 Olympics, part of a match between the Soviet Union and Czechoslovakia. It is very, very cool.
I have a question… How many rule changes and other (non technical) innovations can you pick up from the first five minutes of the clip?***
*** I count
five seven rule changes and two innovations.
