From Rick Altman, "Television/Sound" in Studies in Entertainment:
Critical Approaches to Mass Culture, ed. Tania Modleski,
Bloomington: Indiana U. Press, 1986. 43
Modernism was partly modern in its use of quotation and the assumed knowledge of other texts.
But the intertextuality of television is in some ways more radical, without the central, organizing drive of the author or the specific hierarchies of form given by an established aesthetic.
This quality, the promiscuous and nearly parodic self-referentiality of television, is not quite specific to television in a way that could define the medium. It is a quality... seen as characteristic of a postmodern era.
