3 major imageboards: Futaba Channel, 4chan, and iichan, along with the Overchan index.


An imageboard is an internet forum that revolves around the posting of images. Popular imageboards can be hit with bandwidth consumption reaching up to eighteen terabytes per month and beyond.

Characteristics of imageboards

Imageboards could be most simply described as a bulletin board focused on pictures instead of text posts; they share many of the same structures, including separate forums for separate topics, as well as similar audiences. However, imageboards are much more transitory with content-on some boards (especially high-traffic ones) the thread deletion time can be as little as 10 minutes. The most popular English-language imageboards tend to revolve around Japanese culture such as CG artwork of anime. In Japan, where imageboards are many times more common, topics vary widely, including trains and news.

Imageboards are also different from online galleries in that most of the works posted are not made by the poster, but instead are taken from other online sources—galleries, other imageboards, and edited pictures.

Most imageboards and 2channel-style discussion boards allow (and encourage) anonymous posting and use a system of tripcodes instead of registration. Anonymity is considered to be one of the advantages of an imageboard. Some boards, such as the /b/ (random) board on Futaba and 4chan, have from time to time instituted a ban on names altogether (known as 'forced anonymous/anonymity').

If a user wants to reply to a thread but not bump it, they can put the word "sage" (Japanese: 下げ) in the e-mail field. "Ageing" can refer to either bumping a post or putting the word "age" (Japanese: 上げ) into the email field. It is considered polite to sage when replying to your own thread, but rarely followed. Sageing is often seen as a sign of disapproval, as threads with multiple sages are more likely to be deleted automatically as they fall down the board.

In Japan, the imageboard is a much larger cultural symbol, with one guess putting the total number of posts for Futaba's five /b/ boards (four of which are no longer linked to by the main site) at over 56,000,000 and rising. [1]

Software

There are three versions of imageboard software currently in widespead use: Futallaby (modified from the Futaba Channel script and written in php), Wakaba (written from the ground up in perl), and Kusaba (also written from scratch in php). 4chan uses a heavily modified version of Futallaby.

Imageboards

Futaba Channel

Main article: Futaba Channel
Futaba Channel (ふたば☆ちゃんねる), or "Futaba" for short, is a popular, anonymous BBS and imageboard system based in Japan. Its imageboards usually do not distinguish between pornographic and "clean" content, but there is a strict barrier between two-dimensional (drawn) and three-dimensional (CG and photographic) pictures that is heavily enforced and debated.

4chan

Main article: 4chan
4chan (Japanese: Yotsuba, lit. "four leaves") was intended to be an English language version of the famous Japanese imageboard Futaba Channel. It is by far the most popular English language imageboard website.

Other Imageboards

Although 4chan is by far the largest English-language board, there are a number of other notable boards. iichan/wakachan is a board with a distributed hosting plan; they have a large variety of specifically-themed boards. A number of boards have set up what are called /i/nvasion boards after 4chan banned discussion of attacking other websites; these boards have harassed Hal Turner, Tom Green, and had a segment in Los Angeles's local Fox affiliate (FOX11) aired on imageboard culture, spawning a number of memes about how much "Anonymous" hates people.[2][3]
