Good point Yoshie. The name "popular culture" obscures the difference between the work of artists up through the nineteenth century and the work of mass-marketed pop artists in the twentieth century. This is not to say that the popular culture produced by mass marketing is necessarily inferior to pre-marketing popular culture; I think Hendrix is a great guitarist and so is Robert Johnson....but in a "culture" that can create a national obessession with pet rocks or The Monkees, it's important to remember how much of what is "popular" is the result of brainwashing rather than some spontaneous popular choice. Likewise, if someone is critical of the culture created by mass marketing, it would not be accurate to accuse them of elitism....
