DC is a company that was founded in 1993, and focuses on providing shoes, attire, and accessories for snowboarding and skateboarding.  Even though the focus is to manufacture for participants of these sports, the clothing and shoes are worn by skateboarders and non-skaters alike. The brand is extremely recognizable and popular, especially among the younger generation. The company was started by Ken Block and Damon Way but I am unsure as to who designed the logo. While the logo does often change color according to the clothing or shoes that it is put on the shape and logo design has remained consistent and recognizable.
