Black March is an event created by the internet in January 2012.
The idea of Black March is to not consume anything media related in all of March 2012. That is no books, no magazines, no movies, no music downloads, illegal or legal.
Black March is a reaction to the SOPA and PIPA which is threatening the internet community and its rights to share files.
Hopefully, Black March will target corporations economically and show them not to ever mess with the power of the internet.
