Technology in the year 2000, as predicted in a 1950 issue of Popular Mechanics.
I particularly like the amusing image of businessmen with documents "held up for examination" over their video phones. And yet, in the very same article, they talk about 5-cent facsimile document transmission over "telegraph" lines. I guess it didn't occur to them to link those two concepts: Even in the world they describe in the article, I'd pay the nickel to send the actual document around to my videoconference colleagues, just to avoid putting myself in the ridiculous position of holding paperwork up to a video camera for them to read.
And forget the personal helicopter (I've seen how people drive on the ground): What I want is the $5000 house, where I can clean the living room just by hosing it down.
