Vexing questions

Can someone please tell me the rationale for the continuing existence of Publishers Clearing House?  Nobody subscribes to magazines anymore except doctors' and dentists' offices.  Anyway, thiey no longer even pretends to be selling magazines.  Or books.  Or anything, really.

  So why does this pestiferous organization continue to exist, to broadcast television commercials, and to send out direct mail solicitations.  Why do they still award money to people?  Or are the persons who are televised swooning, shrieking and jumping up and down in their doorways really paid actors?  In short, just what the hell is going on?
  
  While other organizations which have outlived their mission--think Boys Town--have quietly ceased to exist, Publishers clearing House appears immortal.
