The RSS feed ticker is actually a form of RSS feed. The only difference is you don’t get it in your email inbox; instead you get the feeds right on the page you are visiting. Like the traditional RSS feeds, you get only the headlines of the news in the ticker. It is possible to add more content in the ticker; but that gives up the whole idea of this innovative concept. Ticker was introduced to show news update in a very short form which can be placed in a tiny place. You can also see the ticker in television. The moving headlines at the bottom of your television set are also known as ticker.
Facebook is one of the best examples of RSS ticker. If you are a facebook user, you have seen a recent feature in facebook. In the right of your facebook page, you see a live update of your friends’ activities. That is the ticker. It is also extensively used in news sites and more and more websites are now adapting the concept to keep their visitors updated.
