Revolutionary Press Theory was proposed by William Hatchens in 1981 to describe media in countries undergoing revolution against their existing government or foreign domination. It defines revolutionary press as illegal and subversive communication through press and broadcasting with the goal of overthrowing the current government. Revolutionary press usually begins as underground press and is a short-term phenomenon that aims to overthrow the government but may not continue with the same goals once the revolution succeeds. Some countries that have witnessed revolutionary press include Russia, Poland, Iran, Pakistan, Yugoslavia, and Arab Spring states.
