Commonwealth Bank of Australia released an online game for children titled “Coinland” in May 2011. Children can build a character, and earn and save money at the site. The purpose is to allow children to understand the functions of money, and learn the importance of saving and well-planned consumption. The response was explosive. As parents valued its educational effect and recommended the game to their children, the game attracted more and more children users and about 100,000 children participated in the game in 2011 alone. The bank decided to increase the number of game participants to a million by 2015. The bank recently set out an SNS (social network service) marketing targeting customers in their twenties. If a customer takes a photograph of one of the bank branches with a smart phone, post it to Facebook, and open an account at the relevant branch within three hours, the bank gives out a complimentary movie voucher that can be used 12 times a year. The bank is reaching out to customers in their twenties relying on word of mouth via SNS.
