The incorporation of content, whether it is L1-curriculum based or from general knowledge of the world, is not innovative in English Language Teaching.However, CLIL as an umbrella approach has spread the interest in learning English through non-language subject matter to non-European contexts.In this review article, I analyse the development of the Argentinean interest in CLIL from two conference proceedings from the years 2008 and 2009, and two provincial curriculum-based implementations conceived in 2010-2011.While CLIL in Argentina started as a bottom-up approach because teachers and learners wanted to integrate content and language, now CLIL may spread because official curricula determine so.
