Got 11 minutes to spare? We strongly recommend spending that time checking out this film, which was used to promote the 1962 Century 21 Exposition. You can skip the first three minutes, that features two lovebirds running around the city, and get started once said lovers run into the Bell Labs building.
There, you'll find that all those innovations we thought were so radical in the 80s -- speed dial, call forwarding, and call waiting -- were started long ago. Even complex home automation, like turning your sprinklers on or controlling your home's temperature remotely, were thought up long, long ago. Enjoy!
