They focus on the formation of the studios, and exactly how the studios make money (hint: the box office grosses provides little to no actual dollar gain for the studio). However, there's a lot of talk about how these big conglomerates formed, and how the ties between TV channels and movie studios can be mutually beneficial without ever violating antitrust laws.

Pretty fascinating stuff. I'm only a few chapters in, but I love what I've read so far. The segment on the founder of Sony and Sony's insane impact on the movie/TV world was just awesome.
