The United States is wanting to standardize copyright laws between Japan and seven other Pacific countries. Japan has had a unique marketing tool with Doujinshi. Doujinshi is fan made manga that fans can sell at doujinshi conventions, only for that one convention. The fans use copyrighted characters and produce fan manga. Comiket is one of the largest conventions for this type of product. The Japanese publishers have always let these conventions happen because it also helps promote their characters and keeps interest and possible create new interest in their published titles. Thank of it as you get a small taste of the characters and then you want to purchase the whole meal. It would be nice if the U.S. publishers would recognize that this could help them in their business here in the U.S.
