短縮URL
Another reference to URL shortening was in 2001. The first notable URL shortening service, TinyURL, was launched in 2002. Its popularity influenced the creation of at least 100 similar websites, although most are simply domain alternatives. Initially Twitter automatically translated URLs longer than twenty-six characters using TinyURL, although it began using bit.ly instead in 2009 and later developed its own URL shortening service, t.co.
