From Why Things Bite Back: Technology and the Revenge of Unintended Consequences, by Edward Tenner (p.11, 1996, Vintage Books)

Either people lose interest and it becomes a series of literal or metaphoric ghost towns, or it is soon as crowded as the space that people left. … The electromagnetic spectrum that once appeared so ample is now so close to bursting with media and telecommunications channels that re-allocation may leave some users out in the cold.
Does this sound like any phenomenon you might recognize?
