But the greatest Electrical Pioneer of them all was Thomas Edison, who
was a brilliant inventor despite the fact that he had little formal
education and lived in New Jersey. Edison's first major invention in
1877, was the phonograph, which could soon be found in thousands of
American homes, where it basically sat until 1923, when the record was
invented. But Edison's greatest achievement came in 1879, when he
invented the electric company. Edison's design was a brilliant
adaptation of the simple electrical circuit: the electric company sends
electricity through a wire to a customer, then immediately gets the
electricity back through another wire, then (this is the brilliant
part) sends it right back to the customer again.
This means that an electric company can sell a customer the same batch
of electricity thousands of times a day and never get caught, since
very few customers take the time to examine their electricity closely.
In fact the last year any new electricity was generated in the United
States was 1937; the electric companies have been merely re-selling it
ever since, which is why they have so much free time to apply for rate
increases.
-- Dave Barry, "What is Electricity?"
