The MOTif report reveals that of the 50 best-selling comics, 58% of these are not available as e-books. Pirated mangas are often streamed, whereas comic books are scanned. These generally good quality files, either PDFs or images, sell for an average of $15, slightly below the price of the equivalent paper book.
It is also interesting to note that these pirating teams are well organized and able to scan new mangas that are released in Japan.
