I agree with the poster who said he'dstop with Newscorp (Murdoch's empire). And why is he focused on "media" conglomerations? Theres only 2 American car companies, a handful of steel companies, and so on. Its Fox. Fox is on the Left's brain.
Consider the case of a media conglomerate that owns both a radio station and a record label.

This is the kind of interaction between industries that had been prohibited for years in other sectors of the economy. Railroads, for example, are forbidden from owning any of the industries that they serve -- this was because a railroad that owned a coal mine could drive other coal mines out of business by carrying the coal for "free" on its own rail network.
Would he break up George Soros' holdings??? I don't think sooooooo.
