The idea of URL shortening dates to at least 2001.

The first notable URL shortening service, TinyURL, was launched in 2002.

Its popularity influenced the creation of at least 100 similar websites

Most are simply domain alternatives Initially Twitter automatically

translated long URLs usingTinyURL. As of 2009, it uses bit.ly.



Enter a long URL to make tiny:

 In May 2009 .tk, which previously was used to generate memor

able domains via URL redirection, launched tweak.tk,

which generates very short URLs such as

 http://mxtux.tk/ (which redirects to Wikipedia)[citation needed]

On 10 August 2009, the tr.im a notice shortening service announced that "[s]tatistics can no

longer be considered reliable, or reliably available going forward" and

 that they were shuttering the generation of new shortened URLs,

but assured existing tr.im short URLs would "continue to redirect,

and will do so until at least December 31, 2009". A blog post on the site attributed

this move to several factors, including the lack of suitable revenue

generation mechanisms to cover ongoing hosting and maintenance costs,

lack of interest among possible purchasers of the service,

and Twitter's default use of the bit.ly shortener.

 This blog post also questioned whether other shortening services can successfully monetize URL

 shortening in the longer term.

A few days later, tr.im reversed itself on this move,

announcing it would resume all operations "going forward, indefinitely,

while we continue to consider our options

 in regards to tr.im's future" On 14 August 2009, WordPress announced the wp.me URL shortener for

 use when referring to any WordPress.com blog post.

In November 2009, shortened links on bit.ly   were accessed 2.1 billion times. Around that time,

bit.ly and TinyURL were the most widely used URL shortening services

 In December 2009, the URL shortener TO./ NanoURL was launched by .TO. The

 service creates a URL address which looks like http://to./xxxx, where xxxx represents

 acombination of random numbers and letters.

NanoURL currently generates the shortest URLs of all

 URL shortening services,

because it is hosted on a top level domain (the one of Tonga).

This rare form of URL may cause problems with some browsers,

which interpret this as a search term and

 look it up on a search engine, instead of opening it.

 On 14 December 2009, Google announced aservice called Google URL Shortener,

which is currently only available for use through Google

 products (such as Google Toolbar and Feedburner.)

It does, however, have two extensions (standard and lite versions)

 for Google Chrome.

On 21 December 2009, Google also announced a service

 called Youtube URL Shortener
