In Britain, for example, the 1970s saw an array of cultural commentators use the phrase ‘youthquake’ to denote the way young people had been central to the shifts transforming British society since the Second World War. More recent ‘youthquakes’ have also registered on the Richter scale of worldwide change. In 2003, for instance, the term was emblazoned across the cover of Egypt Today, as the English-language Egyptian magazine spotlighted the way the nation’s youngsters were ‘rocking the world of movies, music and TV’. Generally, emphasis is placed on the way cultural meanings are always dynamic – continually formed and reformed as they circulate through (and feed back into) the various sites of production, representation, and consumption. European research also testified to the omnipresence of media in young people’s lives. The chapter also presents an overview of the key concepts discussed in this book.
