A textboard is a simple kind of Internet forum; most textboards require neither registration nor entry of a screen name. Textboards, like imageboards, were invented in Japan, but they remain relatively unknown outside it, in contrast to imageboards (such as 4chan).
One of the key differences between textboards and traditional forums is that textboards allow users to post without registration, and often encourage anonymous discussion. Hiroyuki Nishimura, the founder of 2channel, says that the philosophy behind anonymous posting is that "all information is treated equally; only an accurate argument will work". Many textboards support a form of pseudo-registration by allowing users to use tripcodes, although users tend to post anonymously.
Textboards tend to be much simpler than traditional forums. While forums software such as phpBB or vBulletin supports image or other media embedding, private messaging, polls, and various other features, textboards allow only the posting of text.

2channel was based on a previous text board called Ayashii World, the first big anonymous text board in Japan... Ayashii World, like many anonymous chan boards, experienced so much downtime that its owner began to receive death threats, prompting him to shut down the board in 1998.
