Bible Student movement
The Watch Tower Bible and Tract Society produces religious literature primarily for use by Jehovah's Witnesses. The organization's international writing, artwork, translation, and printery workforce are all baptized Jehovah's Witnesses. Since 2001, the literature produced by the Watch Tower Society is said to have been "published by Jehovah's Witnesses". Prior to 1931, the Watch Tower Society produced literature for the Bible Student movement.
