Even with all of this apparent corruption one can still find 5-10 local radio stations without any big network affiliations. I know what you're thinking, "But Taylor what happened to this awful corruption conspiracy you spent your whole post establishing?" Well television came out years later in the 1930s and if you look at their broadcasting system it is almost completely controlled by large corporations. It's almost as if GE and NBC were learning how to ride a bike with radio and by the time television rolled around they were ready to ride like the big boys. If you ever seen 30 Rock you would get a good insight (albeit comical) into how the media industry is run by corporations like GE.
Now for a comic! Clavin & Hobbes (my favorite)
