<P> Although telegraphic printing systems were first invented by Royal Earl House in 1846 , early models were fragile , required hand - cranked power , frequently went out of synchronization between sender and receiver , and did not become popular in widespread commercial use . David E. Hughes improved the printing telegraph design with clockwork weight power in 1856 , and his design was further improved and became viable for commercial use when George M. Phelps devised a resynchronization system in 1858 . The first stock price ticker system using a telegraphic printer was invented by Edward A. Calahan in 1863 ; he unveiled his device in New York City on November 15 , 1867 . Early versions of stock tickers provided the first mechanical means of conveying stock prices ( `` quotes '' ) , over a long distance over telegraph wiring . In its infancy , the ticker used the same symbols as Morse code as a medium for conveying messages . One of the earliest practical stock ticker machines , the Universal Stock Ticker developed by Thomas Edison in 1869 , used alphanumeric characters with a printing speed of approximately one character per second . </P>
