For the benefit of those new to cryonet and who are interested in predicting 
the future:

In the late 1960s, AH Reeves, a PCM pioneer, gave several lectures to 
learned institutions on his predictions for the future of telecommunications 
by 2000. In the 1960s telecommunications was a lot more tightly controlled 
and therefore expensive, and the idea of using PCM for entertainment (CDs, 
DVDs, etc) was an anathema. Indeed many people thought it would to too 
expensive for ordinary telephones. A sort of PCM was used for secure 
communications during WW2 and the Sigalsy (as it was known) equipment filled 
a room at both ends of the link. It was thought that by 2000 video files may 
be available on demand via wired networks, but no mention was made of 
hypertext, or emails. The text of these lectures can be found on
