We live, like it or not, in the age of the celebrity. High achievers in entertainment or sport have always commanded attention and headlines, but the reach, in today's society, of film and television, and particularly of the social media, has meant that the impact of the "rich and famous" is greater today than it has ever been.
It is increasingly clear that this kind of celebrity can be used to exert great influence over the young in particular, but also to make a great deal of money through endorsements and the marketing of products bearing famous names. Millions of young women around the world choose clothes, make-up, social activities and other purchases, following the recommendations of those whose lifestyles are regarded as wonderfully glamorous and therefore to be emulated.

There is a further curiosity about the modern concept of the "celebrity". The actual achievements or talents of the modern celebrity may sometimes be rather difficult to identify. The Kardashians, for example, seem not to be particularly talented as individuals - but they are, as a family or "brand", famous for being famous. What is undeniable is that they are very successful at promoting themselves, and providing models that many young women and girls try to copy.
The Kardashians exemplify another common aspect of the celebrity cult - the tendency of one celebrity to team up with another. Kim Kardashian is the partner of the US rapper, Kanye West - and David and Victoria Beckham's marriage brought together a top British footballer and a singer from the Spice Girls. In instances such as these, the celebrity impact seems to be more than doubled but is multiplied several times over - and children of the union themselves become celebrities and add to the overall impact.
