ANIME-Impact:- Advancements in fansubbing quality mean that fansubs are now of such quality and free accessibility that the incentive to upgrade (or in some cases downgrade, as from an HD fansub to an SD DVD) to a legitimate copy once a title is domestically licensed may be severely diminished.[ citation needed] An article published by the Yale Economic Review found that "almost all survey participants admitted that possession of a movie download will lower willingness to pay for legal products." Economic instabilities in both the US and Japan have made it hard to gauge the precise consequences of digisubs on the commercial industry, as well, though several Japanese and North American anime studios and distribution companies have pointed to fansubbing as drawing a large amount of profit away from them.

In addition to the streaming video, viewers could pay any price they wished (greater than zero) to download a higher-quality version of the shows. As of October 2009, a large number of new anime are being distributed using this same model through Crunchyroll. The general reaction from the fansub community has been to not subtitle these shows, though in some cases the streaming video is released days after the Japanese airing and in very low quality, leading fansubs to still be done of such shows. Several "fansub groups" have taken to ripping the subtitles from these Crunchyroll releases, editing them slightly, syncing them to HDTV video sources, and then releasing them for free. That said, the apparent increase in support from Japanese animation studios for this new distribution model would suggest that it is working quite well, and the number of fansubbing groups has decreased as many people do not feel a need for fansubs when they can stream these shows legally and for free.[ citation needed]
