However, with the digital age at the start of 2000, each step of the fansubbing process was made easier and cheaper with a dramatic improvement to the visual standards of fansubs. Lee described English fansubbing as having been rapidly globalized over the years in terms of viewership. Lee states that it was the rise of peer-to-peer file sharing software "BitTorrent" that "put fansubbing on the map internationally". Lee states that while other language communities exist, the English language fansubbing community has the greatest pull. US publishers traditionally found fansubbing useful for testing demand and broadening their fanbase, whereas Japanese publishers treat fansubbing as something remote and insignificant. Lee states that some Japanese producers even praise fansubber's efforts at promoting their work overseas. However at the turn of the new millennium in the face of fans' demands for greater immediacy, temporal and spatial disparity in overseas licensing, English as the internationally preferred medium for fansubs, and the increasingly globalized membership of the English fansubbing community, fansubbing groups are becoming less and less willing to follow the unspoken rule. Some fansubbers state that they don't want to abandon the rest of the world because someone bought the region 1 license.
