TV-shows are gaining popularity on BitTorrent year after year. In 2009 a new milestone was reached; for two shows in the top 10 – Heroes and Dexter – the number of downloads on BitTorrent has exceeded the average viewership on US television.
美剧的BT下载人气日渐高涨，刚过去的2009年又是一个新的里程碑。伴着《超能英雄》与《双面法医》的新近上榜，BT的美剧下载人数又达到了一个新高。
The rise of unauthorized downloading of TV-shows is a signal that customers want something that is not available through other channels. Availability seems to be the key issue why people turn to BitTorrent, and this is also reflected in the fact that most downloads occur from countries where the show has yet to air on TV.
BT下载虽让发行方颇为头疼，但也能看出巨大的市场潜力来。大量的BT下载表示消费者无法从其它渠道满足他们的需求，而更多的海外下载量更体现了海外市场的前景。
