Black Box Stock Tickers


 

The Black Box Ticker hit Wall Street around December of 1930.  The Teletype Corporation began developing the technology around 1927, and after the crash of October 1929, stock brokers needed a faster, more reliable machine.

By 1934, The New York Quotation Company had switched almost exclusively to the black box ticker.

The black box went through a few changes in the early years, and Western Union began changing over in 1938 to the new 5A model, converting many older, slower machines to sports tickers.

Well over 20,000 were produced into the late 1950's.
