Since 1998, the Casia Corporation Holland have been working on The Definitive TLA Wörterbuch to help people find their way in the ever growing intellectual chaos caused by the late-twentieth century tendency to use as many acronyms in daily communication as possible. Especially acronyms with a length of three letters have been and continue to be immensly popular, not only in Information and Communication Technology circles, but also among people in more mundane fields of labour; a tendency that has mushroomed with the advent of mobile communication and the combined growing popularity of Short Message Services.
At present, there are 7818 TLAs in the database.
Of these, 4597 are distinct, out of 17576 possible (26.15%).
