[INTRODUCTION] Leet (or "1337"), also known as eleet or leetspeak, is an alternative alphabet for many languages that is used primarily on the Internet, in which standard letters are often replaced by numerals or special characters. For example, leet spellings of the word leet include 1337 and l33t; eleet may be spelled 31337 or 3l33t. Leet speak grew and became popular in online games such as Doom in the early 1990's as a way of suggesting that you were a hacker (h4x0r), and therefore to be feared. The term leet is derived from the word elite. The leet alphabet is a specialized form of symbolic writing. Leet may also be considered a substitution cipher, although many dialects or linguistic varieties exist in different online communities. The term leet is also used as an adjective to describe formidable prowess or accomplishment, especially in the fields of online gaming and in its original usage-computer hacking.
[HISTORY] Almost a decade before Tim Berners-Lee's World Wide Web saw its first light of day back in 1991, leet speak was born. Back then when the internet was coming up, most search functionalities simply looked for keywords in text to show relevant documents. Hackers weren't very keen on having their information displayed on websites, bulletin boards, newsgroups or any other place, so they started to replace certain letters in words. It started out with simple vowel substitutions like a 4 instead of an A, or a 3 instead of an E. This meant that topics like cracking or hacking remained undetected. One other (conspiracy) theory is that leet speak was invented as a way to beat automatic government surveillance programs, such as the legendary Echelon program.
In that period leet speak existed only in small circles, and was only used when necessary. It originated within bulletin boards, where someone having an ""elite"" status meant he or she was allowed access to file folders, games and chat rooms. But it wasn't until the addition of internet connectivity to one of the most influential titles in the video games industry, Doom and Doom II that the use of leet speak exploded. From there on leet speak evolved from a method to mislead search functionalities into a language for online gamers to describe formidable prowess or accomplishment. Phrases such as "1 4m 3l33t!" (I am elite!) were thrown around to demonstrate someone was an experienced gamer (or hacker).
