TinyURL is a URL shortening service, a web service that provides short aliases for redirection of long URLs.
Short URL aliases are seen as useful because they are easier to write down, remember or pass around, are less error-prone to write, and also fit where space is limited such as Twitter.
Kevin Gilbertson, a web developer, launched the service in January 2002 so that he would be able to link directly to newsgroup postings that frequently had long and cumbersome addresses.
