i wanted to ask you if you had any suggestions for essays or books about the institutional practices of new media companies or suggestions re political economy studies of new media?  what i had in mind were scholarly versions of books like cringely's accidental empires.  even a more updated version of that book would be useful.  any thoughts in this regard?
