Futaba Channel

, or Futaba for short, also sometimes called 2chan (not to be confused with 2channel), is an imageboard in Japan. A popular Japanese website, it deals with a wide variety of topics, from daily personal problems to junk food, sports, ramen, and otaku and underground culture.
Origin.
Futaba Channel was set up on August 30, 2001, as a refuge for 2channel users when 2channel was in danger of shutting down. It started as a textboard but eventually added imageboards based on the Gazoubbs software. The English-language imageboard 4chan website was based on Futaba.
Concept.
Futaba Channel consists of about 60 imageboards (three of which are oekaki boards) and about 40 textboards, with topics ranging from daily personal problems to junk food, sports, ramen, and pornography. There is also a place to upload general non-image files. Futaba is powered by a custom script based on GazouBBS. The Futaba script is open source and is used to run many Japanese and English imageboards.
Culture.
Futaba has spawned a number of visual gags and characters; the OS-tans would be one such meme that has spread to western internet culture. Some of the characters that appear on Futaba Channel have entered the real world in the form of various real-life goods, such as figures, dolls or images printed on pillows. Such items are mainly produced by Japanese dōjin artists and groups.
Non-Japanese Internet users sometimes refer to Futaba Channel as "2chan," due to the address of the site. It is frequently unclear whether this is intended to mean Futaba Channel or 2channel, and sometimes it even refers to both, as if they were a single website. To eliminate confusion, the names "Futaba" and "2channel" are often used.
