I've mentioned it here before, there is a movement amongst media and providers to dumb down the population. Move the charmless* that broadcast intelligent content to premium-level packages and reinvent the current "smart" channels to cater to dummies. I remember when A&E was a decent station, and The Discovery Channel also.
And TLC was called, "The Learning Channel", they used to show surgeries and other neat science shows.
The knee surgery was funny because at one point the knee squirted out liquid a good distance and the surgeon just jams his finger in the hole.
I still get a good laugh at that.
