In May 1877, an advertisement was produced for Bell’s newly invented telephone. It modestly claimed that the telephone was superior to the telegraph for three reasons: “No skilled operator is required, but direct communication may be had by speech without the intervention of a third person. The communication is much more rapid, the average number of words transmitted in a minute by the Morse sounder being from fifteen to twenty, by telephone from one to two hundred. No expense is required, either for its operation or repair. It needs no battery and has no complicated machinery. It is unsurpassed for economy and simplicity.”
