Japanese mobile social network Line announced its latest quarterly financial results yesterday, with revenues for its core business up 104% year-on-year to $192m. The company also finally gave some active user numbers (as opposed to registered users, its preferred metric in the past). Line currently has 170m monthly active users, with 87m of them in its top three countries: Japan, Taiwan and Thailand. However, the company stressed that it now has more than 25m users in the US, 30m in India and 10m in Colombia, as a way of showing its appeal is stretching beyond Asia. Note, those latter numbers relate to registered rather than active users. Line’s mixture of stickers, games and other content is proving popular, then, but the company’s plans to “accelerate” its global expansion will be watched carefully by Western marketers, to judge when the best time is to experiment with Line.
