Users can share favorite Manga sold in LINE Manga in a timeline of LINE.
Because there is a trial reading function in LINE Manga, users can confirm contents before purchasing them.
This is a big menace for other Japanese e-book services. About 30,000 sale numbers are the hugest in e-book services of Japan. In addition, the publishing companies join in LINE Manga are more than 50. Furthermore, LINE has already had users more than 45 million in Japan. It is huge in all.
By the way, I think that LINE starts the social music service someday. e-book and the music are already virtual goods like a stamp(sticker). It is natural for LINE to treat all of them. Possibly the trial of the other day may be its sign. In Japan, LINE is already contents platform as well as messaging apps.
