Parker Pen Pals: Computerized Match Making
At the 1964 New York World’s Fair, Parker Pens provided a novel service for the time: Its pavilion used a computer to connect personalities on opposite sides of the world. You could jot down contact details, along with numbered interest selections, and (perhaps) get connected with a distant but like-minded person. Jump-cut to today, and we have eHarmony, complete with a 258-question inquisition into each participant's character.
