Ticker Tape

Back in 1927, stock information (e.g., prices) were passed on through telegraph.

Yep.

Still with us?

The info was printed on thin paper known as ticker tape. Back in the day, this paper was synonymous with the stock market, and people used to throw the stuff around during parades. By the 1960s, the traditional ticker tape was no longer needed; there were better and faster ways to transmit stock price info.

Today, it's all done electronically. No more dead trees, thankyouverymuch.

So, now, ticker tape refers to the stream of stock prices and information that come through, usually on a mobile device or screen of some sort.
