NBC Moves Away From Family Fare (washingtonpost.com)

The mistake the networks always make is to purposefully target specific demographics when trying to create/choose new shows. Start with a great premise and good writers first, then find the acting talent, then find a strong director. The demographics will come to you. Was The West Wing created with a demographic in mind? How about The Sopranos? Law and Order? Maybe I'm being naive here, but I believe quality does eventually attract audiences. Look how long Seinfeld took to build a following. Or The X-Files.
