We lived in a small town. Telephones looked like this.
You said the number, and she (operators were always women) made the connection for you via a switchboard.
When I was about 10 years old, our town finally got rotary dial telephones, and all numbers were changed to seven digits.
Television was also in its infancy. Black-and-white reception was grainy and had a tendency to become unstable. A particular problem was the rolling of the picture up or down due to interference.
When color television was first introduced, you had to reset the picture's hue and color with knobs every time a color broadcast came on. This too took lots of fussing or the grass would be blue and the actors would have purple faces.
A picture phone, the combination of television and telephone, was the stuff of science fiction.
In an instant, I can access information about almost anything though my phone.
