Link to radio transcript from 2000 about Echelon.

Edit: pulled out a quote:

MICHAEL BRISSENDEN: The existence of the Echelon network was only confirmed a few weeks ago when US National Security Agency documents were declassified. Essentially it's a surveillance network capable of intercepting any telephone call, fax or e-mail made on earth. Echelon is run by the US National Security Agency using satellites and ground bases in Britain, Australia, Canada and New Zealand. It can sift through a million electronic messages every half hour.
