2channel, also known as 2ch, is a famous Japanese textboard. A textboard is a place where people can post messages online. It was started in 1999 by a man named Hiroyuki Nishimura.

By 2007, it was the most popular online community in Japan. It was very powerful, almost like television or radio. The site had about ten million visitors. It also saw 2.5 million posts every single day.

The site works through a system called anonymous posting. This means people do not use their real names when they talk. Nishimura wanted people to share ideas without being afraid. He thought that if people had names, they would just attack each other. Without names, everyone is treated the same. Only a good argument matters, not who said it. This way of talking helped inspire other sites like 4chan. Users can talk about many things like sports or even science.

2channel grew from older technologies like Usenet and bulletin boards. Two earlier sites, Ayashii World and Amezou, helped lead to its creation. Ayashii World was the first large anonymous board in Japan. Amezou introduced the idea of a textboard where new posts move old ones to the top. Nishimura advertised his new site on Amezou in May 1999. He called it "Amezou's second channel." He started the site in a college apartment in Conway, Arkansas.

There have been many serious problems with the site over the years. In 2008, Nishimura faced over one hundred lawsuits for defamation. Defamation is when people say things that hurt a person's reputation. In 2012, police looked into the site regarding illegal drug sales. A big hacker attack happened in August 2013. This leak exposed the private info of 74,000 users. This included names, addresses, and even credit card numbers. This happened through a paid service called the Kako Log.

In 2014, the site split into two different versions. A man named Jim Watkins took control of the main web address. Nishimura said this was an illegal hijacking of the site. In response, Nishimura created a new site called 2ch.sc. One version eventually changed its name to 5channel to avoid legal issues. Today, different groups own these different versions of the site. They still host many different boards for people to use. The history of these sites shows how much the internet can change.
