I'm still pretty sure the stories about flagging calls for mentioning keywords in the 90's were urban legends. The sort of computing power to do that didn't exist then. It's a conspiracy theory pasted onto a kernel of truth (Echelon). Even after snowden there is a lot of the same stuff going on. The stuff he leaked sure didn't show that the NSA was doing some sort of active analysis on all communications. Though at least now it's probably within the realm of technical possibility.
