I myself have had work distributed electronically without my prior permission, and with no compensation to me; that is illegal and also highly annoying (esp. when some dork runs it through a scanner and a spell-checker and what comes out is not what I wrote. Nothing book-length, and with unique words, will come out of that in the same shape it went in...just so you know...one time "soldiers" turned into "sold hers" which sure makes hash of a sentence like "Eight soldiers came out of the woods" ("Eight sold hers came out of the woods?????")

If you're worried about your favorite TV shows, write the network and the production studio, and tell them to pay their writers fair residuals.
