miji.beTinyURL, one of the earliest short URL services, was launched by Kevin Gilbertson in 2002. On the internet of that time, there was a problem: when you pasted a long URL into a bulletin board or an email, it would wrap onto a new line partway through and the link would break. Usenet (netnews) users in particular were troubled by this problem. Gilbertson solved it with the simple idea of "converting a long URL into a short URL and redirecting it," and TinyURL went on to remain in use as a service. TinyURL's domain, tinyurl.com, has 11 characters and can hardly be called short. At the time, however, the idea of making URLs shorter was not yet widely known, so rather than the shortness of the domain, what was new was the function itself: "being able to convert any URL into a short URL of fixed length."
A major turning point in the history of short URLs was the arrival of Twitter (now X) in 2006. Because URLs had to be shared within a strict limit of 140 characters, demand for short URL services grew. bit.ly, which appeared in 2008, went beyond simple URL shortening by opening a click-counting feature to general users as well, evolving the short URL into a "marketing tool." In 2009, Google launched goo.gl and Facebook also set up fb.me, and big tech companies entered one after another. However, Google announced the shutdown of goo.gl in 2018, and afterward stopped accepting the creation of new short URLs. This withdrawal raised the question of how long short URL services will last. At the end of 2024, Google announced that goo.gl links that had received no traffic would stop responding after August 25, 2025, and explained that other links would continue to work as before. This means that, regardless of the intentions of those who created them, the lifespan of links is decided by the operating company's judgment.
In numbers, short URLs are used on a large scale. Bitly states on its own website that more than 2 billion links and QR codes are created each year, and that more than 100 billion clicks and scans take place each year. These are figures published by the company as of October 2026. The fact that a single company's service reaches this scale shows that short URLs are used every day, just like search and email. In large campaigns, clicks concentrate on a single short URL, and the numbers for that one link are sometimes treated as an indicator for measuring the response to the whole campaign.
Here is some surprising trivia about short URLs. First, the domains used by short URL services are the product of a race to cut characters. `t.co`, which X (formerly Twitter) uses to convert links, and `j.mp`, which was registered just for shortening, are 4 characters long, combining a 1-character label with a 2-character top-level domain, and only 3 characters if you leave out the dot. Some, like `dwz.cn` used in China, are 6 characters long, but all of them are shorter than the domains companies normally use. Because no top-level domains shorter than 2 characters are in use, these 4 characters are close to the lower limit for the length of a domain. Next is the story of the "lifespan" of short URLs. Some short URLs fall into link rot within a few years of being created. The main causes include the shutdown of the short URL service, changes to the redirect destination, and expiration of the domain. This problem is also called "Digital Decay." Because a short URL is an entry point that holds only the forwarding instruction, once that instruction is lost, only the string of the link remains and its destination can no longer be known.
Regarding the future of short URLs, there are several developments. With the spread of QR codes, the role of short URLs is expanding from "URLs read by humans" to "URLs read by machines." A URL is embedded inside a QR code, and the shorter the URL, the smaller the QR code, so short URLs have the property of combining easily with QR codes. The concept of a "decentralized short URL" that makes use of blockchain technology is also being discussed. Conventional short URLs depend on centralized servers and so carried the risk of the service shutting down, but if redirect information is recorded on a blockchain, permanent links can in theory be achieved. However, because of issues with blockchain processing speed and cost, challenges still remain before practical use. Short URLs, with a history of more than 20 years, have changed their form along with the changes in the internet.
