A picture messaging app in South Korea, which bears a striking similarity to Snapchat, has taken off all around Asia. With filters, self-deleting image messaging and a function to store videos as ‘stories’, the Snapchat clone, called Snow, is proving how social messaging giants face a struggle to grow in fast-growing Asian countries. With around 30 million downloads since its introduction in September, Snow is now growing in China where Snapchat is banned. According to Han Dong-keun, a spokesman for its parent company Naver, Snow is looking to make the most of China’s 700 million user internet market. Mr. Chae, a venture capital investor, has said that Korean founders no longer target the US market, where they often fail, but are now targeting the growing Chinese market that “seems to be more welcoming for Korean technology and culture than the Western world ever was”.
