“The shelf life for Viacom’s reality shows like “Teen Mom” and “Jersey Shore” is shorter than it used to be, because why watch a reality show rerun when you can watch something on YouTube or Twitch, or play around with Vine and Snapchat, or Clash of Clans or whatever. So the company has to knock down the value it had attributed to those shows in its catalog. The same goes for some reruns the company had purchased from other providers.”
