This page is made to catalog all 4chan boards addition dates. This does not cover name changes. Blue means there is a board additon, red means there was a removal, orange means it was frozen (very rare). It will still show red even if it is just a temporary removal or a possible, date uncertain removal. The textboards have less information written on them in this timeline because I've chosen to focus on information regarding the imageboards, but if you really want to have information about them in this page, the next sentence has information about how you can contact me. If you see any dates that look out of place or have any information about these additions/removals, feel free to send me an email at 4chansociety@gmail.com. This is mainly for the GET catalog.
