What Happened to Unaired Pilots?
 

I used to remember a time when it was possible to get a hold of a pilot for a show that never aired. Nowadays, it's virtually impossible. Yet, pilots are still being made and shelved every season. I wonder what happened.

I too have always wondered this. A few years back I was friends with someone in the industry, managed to get a few- but in general, I have about 50 most are from the 60's and 70's have no clue where they go. In an age where so many things are digital, leaked and shared- it amazes me how hard they are to find.
