Shortened URL’s date back to 2001  but have become extremely popular since the inception of Twitter. A URL that is 60 characters long can be shortened to about 15 characters by simply using a URL shortening service. Once of the most popular services to date is TinyURL which was used by Twitter up until 2009. Now Twitter uses bit.ly to shorten URL’s.
