Ticker tape is a type of printed tape that displays stock prices and other financial information in real-time. It was invented by Edward Calahan in 1867.
The first ticker tape machine was created by Calahan, who was an American inventor and engineer. The machine printed out stock prices on a continuous roll of paper.
Ticker tape was originally used for displaying stock prices on the floor of the New York Stock Exchange. It was a revolutionary innovation that allowed traders to quickly and easily access up-to-date market information.
The name "ticker" comes from the sound of the machine's printing mechanism, which sounded like a clock ticking.
What Is Ticker Tape?
Ticker tape is a type of printing that displays stock prices, news, and other information in a rapid and sequential manner.
It was invented in 1867 by Edward Calahan, a telegraph operator who worked for the Gold and Stock Telegraph Company.
The first ticker tape machine was called the "printing telegraph", and it printed stock prices and other information on a long strip of paper.
This early version of ticker tape was used to keep track of stock prices in real-time, allowing investors to make informed decisions quickly.

What Is the History of Ticker Tape
The history of ticker tape is a fascinating story that dates back to 1867. Edward A. Calahan invented the first telegraphic ticker tape, which printed stock prices on a paper strip.
Initially, ticker tape machines were based on telegraph wires and used specialized keyboards to convert stock data into Morse code. This was the height of technology at the time, and it was incredibly clever.
In 1871, Thomas Edison improved and patented the device, making it widely used by bankers and brokers across the country. The original systems had a 15- to 20-minute delay between the time a message was sent and when it was delivered.
Over time, ticker-tape machines got faster, but they still had a delay. Brokers needed to be near the stock exchange for the latest information.
Here's a quick rundown of the major milestones in the history of ticker tape:
- 1867: Edward A. Calahan invents the first telegraphic ticker tape
- 1871: Thomas Edison improves and patents the device
- 1960s: Mechanical ticker tapes are replaced by electronic ones
- 1996: Real-time electronic tickers are launched
By the 1880s, there were about a thousand stock tickers installed in the offices of New York bankers and brokers. This shows just how fast the technology was spreading.
Today, you can still see ticker tapes on financial news websites, stock trading apps, or financial TV channels like CNBC TV18. They display real-time information about stock prices and trading activity.
