The Watchtower
In 1909 the name was changed to "The Watch Tower and Herald of Christ's Presence". In 1920, the Watch Tower Society reprinted all issues from 1879–1919 in seven volumes, known as the "Watchtower Reprints", which have since been reprinted by various Bible Student groups. On 15 October 1931, the magazine was renamed "The Watchtower and Herald of Christ's Presence"; in January 1939, "The Watchtower and Herald of Christ's Kingdom"; from March 1939 until the present, its full name has been "The Watchtower Announcing Jehovah's Kingdom".
