Which organisation is widely known for leaving Bibles in hotel rooms?

The Gideons International, a Christian organisation, has been placing Bibles in hotel rooms for over 100 years. The tradition started in 1908 when two travelling salesmen, John H. Nicholson and Samuel E. Hill, met in a hotel room in Boscobel, Wisconsin. They realised that there was no Bible in the room, and they decided to do something about it. They founded The Gideons International and started placing Bibles in hotel rooms as a way to spread the Gospel.

The Gideons' mission is to make the Word of God available to as many people as possible. They believe that by placing Bibles in hotel rooms, they can reach people who may not have had the chance to hear the Gospel otherwise. The Bibles are placed in a prominent location, such as a bedside table, where they are easily accessible to guests.

The Gideons International is a non-profit organisation that relies on the donations of its members to fund its mission. They have placed over 2 billion Bibles in hotel rooms worldwide, and they continue to do so today.
