Proof almost if not all boxing styles have been around for over a century.

Here is a newspaper from San Francisco in 1913. An image of the many new boxing styles that emerged in the sport's rich history. Captions read from left to right as: "Jem Mace was one of the first to establish a scientific style of boxing" "John L. Sullivan brought slugging into favor" "Jim Corbett had everybody imitating his jab and jump style" "After Fitzsimmons knocked Corbett out fighters tried to use his 'shift' and his hard hooks" "Some of the crouches worked wonders" "Jeffries started the crouching style" "Champion Ritchie has brought the straight-standing style in again" http://i.imgur.com/bAvZYKt.png Original source: http://chroniclingamerica.loc.gov/lccn/sn85066387/1913-08-01/ed-1/seq-10/
