Žižek's idiosyncratic style, popular academic works, frequent magazine op-eds, and critical assimilation of high and low culture have gained him international influence, controversy, criticism and a substantial audience outside academia. In 2012, "Foreign Policy" listed Žižek on its list of Top 100 Global Thinkers, calling him "a celebrity philosopher" while elsewhere he has been dubbed the "Elvis of cultural theory" and "the most dangerous philosopher in the West". Žižek has been called "the leading Hegelian of our time", and Rothenberg and Khadr (2013) state that he is the "foremost exponent of Lacanian theory".
