ANIME-Legal And Ethical Issues:- In countries subscribing to the Berne Convention, fansubbing is illegal as it constitutes copyright infringement. However, fansubbers have traditionally held themselves to a common code of ethics and do not commonly see themselves as pirates. Many fansubs contain subtitle text that reads "This is a free fansub: not for sale, rent, or auction" that pops up during eyecatches Marketing concerns for distribution companies create a gray operating zone for fansubbers. While on the one hand it is true that products like Fist of the North Starare released and licensed in America, only part of the series is available. A fan willing to buy the whole series would find it impossible. However, the lack of support of these products is often a factor in the decision to not continue releasing a series. The costs of licensing more of the series might not be possible without a successful release of the initial offering. Supporters of fansubbing point to an alleged positive impact it has had on the anime industry through its function as publicity. There have been several shows that were at first overlooked for US distribution, only to be picked up later when fansubs helped create a buzz about the franchise. [ citation needed]
