Audience manufacture in historical perspective: from broadcasting to Google.

The question of what is new about new media has become a central topic of discussion in new media studies. This article frames within that question a historical and comparative analysis of the process of audience manufacture, and attempts to overcome the limitations of previous literature on the internet by situating the discussion within the political economy of communication. The main topics addressed in the 'blindspot debate' - the debate regarding the audience as the commodity produced by advertising-supported media - are used to guide an examination of audience manufacture in broadcasting media, and to contrast it with the manufacture of the online audience. The evolution of online advertising, in particular its relationship with search engines, serves as an entry point for questioning some well-established assumptions about the role of audiences in commercial media systems.
