I've read somewhere about a t.v. station that just carelessly tossed films into a dumpster. I'm sure there were many that did this. Being a former dumpster diver myself (it's not uncommon), someone would have snagged some films up in a heartbeat, in hopes of reselling them perhaps. But, I would only reach in a dumpster so deep to recover stuff. You wouldn't want to stick your hand in there and get bitten by a rat. Of course, those day are long gone as t.v. stations haven't broadcast actual film in decades. I used to trash training videos for a store I managed when they became obsolete without giving it a second thought.
