1. Introduction

1.1 What is fansubbing?

Fansubbing, or fan subtitling, is the process of taking a video or movie in a foreign language and adding your own subtitles to it so that people who don't know the original language can watch and enjoy the work. The phenomenon of fansubbing is most prevalent in the anime community, since most anime originates in Japan and must be translated before it can be widely shown outside of Japan. However, fansubbing certainly is not limited in scope to anime; it can be employed whenever one wants to make a motion picture work accessible to people unfamiliar with the language.
