The economics depends on reducing the 2000 DVD's to the number that are
actually used.  Commercial popularity of DVD's for videos and technical manuals,
etc.  once made DVD copying businesses practical.   Now some techical manuals
are distributed in the form of a tablet that replaces a stack of DVD's
while others
are available online.

Many of the same companies that provide mass DVD copying and mailing are
now doing USB flash drives.   See

Moving to USB will not be a simple project, especially since the goal
is to include
less popular systems so relies on testing by others.

DVD's provide a durable collection of older versions for those who have DVD
readers.   USB keys tend to collect malware, so recycling is not something that
can be done by ordinary users, and there will be more failures than for DVD's.
