This guy does a lot of in depth videos on extreme sports and their history. He just uploaded this one on unicycling today, and it seems like he did a fairly good job at explaining it. It hasn't got every detail but it is made for general audiences and he covered quite a bit of ground. It seems more intent on explaining the sport rather than bashing it, so cheers for that. Also, near the end he gave our boys Clement, Jack and Mimo with a nice shoutout and admiration of style.
