Line, the mobile messaging company from Japan, is borrowing a strategy from Facebook after it launched a lightweight version of its service for Android devices in emerging markets. The service counts 205 million monthly active users, but over half of those are located in just three countries: Japan, Thailand and Taiwan. With this new app, Line is hoping that a smaller and less bloated version will help it gain traction with users in emerging markets who often have cheaper devices and more limited internet connections. Facebook is the master of this approach: its latest emerging market app, Facebook Lite, launched in June following a quiet beta rollout in January.
