News ticker - Definition and Overview

A News Ticker is a small screen space on News television networks dedicated to headlines or minor pieces of news.
News stations (CNN for example) will have the bottom tenth of the screen devoted to a horizontally scrolling banner giving off news mini news stories. Use of well known abbreviations optimizes the performances of such systems.

Financial news channels often have two or more tickers progressing at different speeds.

Networks that focus on sports often use a slightly different system, where the scores and status of current and finished games are displayed one by one, along with minor sports highlights.

The name ticker comes from the paper ticker tape machines which once printed news on to a moving paper tape.
