A possible and troubling outcome of this may be that "controversial" scenes are removed from classic films entirely, because advertisers don't want to be associated with them. We've already seen disclaimers added to movies that are "problematic" like Gone with the Wind or Breakfast at Tiffany's.
When push comes to shove, will Media Co. turn down millions from Coke just to keep a 30-second scene in a film? I'm not optimistic.
