Does anyone out there know where I can get the following sorts of figures?
 
1.  Media ownership--Who owns whom? Which media organizations own which, and
      what non media organizations do they own or own them?
      Any dollar figures available?  Dates of new conglomerations?
      Is there a way to get some older figures so that changes can be traced?
      Becuz these r in such flux, I would esp like some recent figures (though
      they can be from,say, 3/93 instead of 5/94).
      Any handy summary tables out there?
 
2.  The most popular books and magazines--by week, by year?
    Also, any handy sum tables?
 
I'm interested in both hard copies (books, periodicals, etc) and online.
The easier to obtain, the better, but I'm open to all suggestions, even the
tough ones.
 
Thanks!
