U.S. Stock Symbol History
In the United States, modern letter-only ticker symbols were developed by Standard & Poor's (S&P) to bring a national standard to investing. Previously, a single company could have many different ticker symbols as they varied between the dozens of individual stock markets. The term ticker refers to the noise made by the ticker tape machines once widely used by stock exchanges.
The S&P system was later standardized by the securities industry and modified as years passed. Stock symbols for preferred stock have not been standardized.

Famous quotes containing the words stock, symbol and/or history:
“And anyone is free to condemn me to death
If he leaves it to nature to carry out the sentence.
I shall will to the common stock of air my breath
And pay a death tax of fairly polite repentance.”
—Robert Frost (1874–1963)
“In a symbol there is concealment and yet revelation: here therefore, by silence and by speech acting together, comes a double significance.... In the symbol proper, what we can call a symbol, there is ever, more or less distinctly and directly, some embodiment and revelation of the Infinite; the Infinite is made to blend itself with the Finite, to stand visible, and as it were, attainable there. By symbols, accordingly, is man guided and commanded, made happy, made wretched.”
—Thomas Carlyle (1795–1881)
“The history of medicine is the history of the unusual.”
—Robert M. Fresco, and Jack Arnold. Prof. Gerald Deemer (Leo G. Carroll)
