Caller ID: Two Steps Up, Two Steps Back

Let me see if I understand this: The telephone industry spends countless millions of dollars developing technology that will allow my phone number to be displayed to anyone I call if they have something called “caller ID” (“GTE Launches Controversial Caller ID in State Today,” June 15).

Then the telephone industry spends countless million of dollars developing the technology that will prevent my number from being displayed, thereby returning us to where we were on June 14.

Now, that’s progress!
