A news ticker is the small screen space on typically displayed by news television channels dedicated to presenting headlines or less important pieces of news.
Computer users can also add news tickers to their screen by relying on dedicated software solutions.
Most of these applications are targeted at certain predefined news channels, but users are largely allowed to add their own favorite RSS feed and to customize its appearance and updating frequency.
News tickers usually have hyperlinks so that users will have the possibility to further analyze and explore the headlines that caught their attention.
