If you want an example of what happens when a public broadcasting resource is privatized, all you need to do is look at TLC.
The channel has been criticized for departing from the original nature of its programming, by airing shows of a controversial nature with what is described as having no educational value. TLC programs that have come under fire from critics and the media include Toddlers & Tiaras, Sarah Palin's Alaska, Extreme Couponing, 19 Kids and Counting, Kate Plus 8, Sister Wives, Long Island Medium, Here Comes Honey Boo Boo, and My Big Fat American Gypsy Wedding.
I did not know that TLC got its start as a government funded venture. Just look at the train wreck its become since it was aquired by private interests.
