What's with the facination with the Echelon?

The codename for the NSA's (National Security Agency) high-tech information-interception system. Echelon has a collection of satellite dishes (supposedly Echelon is made up of a network of satellite dishes)overseas, basically in all english-speaking countries (including America, Canada, England, Australia, and New Zealand...).

Echelon is said to intercept, on a daily basis, billions of e-mails, phonecalls, downloads, satellite transmissions, faxes, and any other form of digital media. This is used to help locate possible terrorists in the new age of cyber warfare.

Echelon was made popular, and positively (as in, in a good way), by Tom Clancy's Splinter Cell. ^_^
"Don't worry about the Echelon system keeping a record of your e-mails! They don't really read all of'em. Stop being paranoid and live your life! >_< "

Computer system operated by NSA for purposes of locating possible threats through scanning of electronic communications.
The system takes random samplings of all communication types including voice, and scans them for keywords, such as anthrax, in most languages. If it finds one, whatever uplink you used will be listened to more often, and common occurances of keywords may promt the system to alert a human operator.

Unless you are talkin about that sorta stuff all the time, you'll never even be noticed.
