The Red de PopularizaciOn de la Ciencia y la Tecnologia en America latina y el Caribe (RedPOP) (Latin American and Caribbean Network for the Popularization of Science and Technology) was created 25 years ago as an expression of a movement that started in the 1960s in favour of a scientific education. The purpose of this movement was to incorporate science into the general knowledge of the population by communicating science through different media, products and spaces such as museums and science centres. Since then, the movement has acquired considerable strength in Latin America and RedPOP has been a key factor to the development of this activity in the region, although several challenges still have to be addressed.
