Sales Support

Reading system at no cost

When it comes to ebook promotions, offering potential buyers a “Free Read” is a must. However, not only does this necessitate the creation of a “Free Read” e-file, but also the development of an authoring system, viewer, database and content server.

Costs for this can quickly run into 6 digits, a tremendous financial burden for the content holder. Profits that were destined to be rolled over into production are reduced, a significant worry for the ebook industry as a whole.

To tackle this, we have begun offering our own cutting edge reading system used in our SOKUYOMI service at no cost. Just adding a few simple tags enables your users to enjoy trial reads through your own website.

Ebook as digital novelty

Published manga and magazines until now have often contained the “Freebie”, small items that came with the material as a bonus to the reader. However, “Freebies” came with their own complications, such as defects, inventory management and ingestion by children. With the digital content revolution comes a new definition of the “Freebie”.

As a “Digital Freebie”, we now offer a coupon system. Use of this system enables us to act as traditional advertising firm and deal directly with the content providers.
