"We learn that the first sport to be filmed was boxing, in 1894."

Edison's foresight and genius was evidenced yet again in 1893, when he constructed the first-ever film production studio, the Black Maria, or the Kinetographic Theater. This delightful 2-DVD set from A2ZCDS.com contains 132 absorbing short films produced by the Edison Company between 1891 and 1898.

Leonard-Cushing Fight (1894) - Filmed in Edison's Black Maria Studio on the 14th of June 1894, this clip features the much talked about boxing bout between Leonard and Cushing. It is one of the first proper boxing footage, and what a match it was. Shot at a time when the rules in boxing were kept to a minimum, the fight between the two is very intense. The referee can hardly interfere, and it is a good thing that he does not. It is interesting to watch even if you are not a boxing fan.
