One of the reasons so many pop performers are described as 'pop stars' is that they are quickly promoted to this status by their management, through the use of cleaver publicity such as a famous boyfriend/girlfriend or attendance at premiers.

However a true pop star has a lasting significance, and has "brand significance" across a wider market over a period of time.
Dyer proposes that a star is an image not a real person that is constucted (as any other aspect of fiction is) out of a range of material (eg. advertising, magazines etc.)
Stars are made to appeal to audiences and generate revenue, therefore companies nurture stars and reproduce successful prototypes.
