Nueva ola
The nueva ola (Spanish for "new wave") was a cultural phenomenon that took place in several Hispanic American countries between the late 1950s and the mid-to-late 1960s, linked to the spread of new musical styles aimed at young people—such as pop, rock and roll and the twist—which "constituted the fundamental channels for the transformation of consumption, leisure, and youth fashions" of the time. It was a regional manifestation of a phenomenon occurring in much of the Western world: the emergence of a new market segment made up of young people with their own habits and shared codes that set them apart from their parents' generation.
