Yes, and NetFlix is a great example. Prior to the existence of NetFlix video piracy was extensive and widespread, once NetFlix appeared that piracy was greatly reduced as the "value" was there (it was more convenient to pay NetFlix than to figure out how to pirate stuff). It won't be "zero" of course but it was effective enough that content companies have emphasized that model over encrypted optical media.
