'Lost' and 'Heroes' ended their series runs on top -- on top of the most-pirated shows list of 2010.

According to TorrentFreak.com, 'Lost' logged 5.94 million illegal downloads for a single episode. 'Heroes,' a show with much lower Nielsen ratings, had an episode downloaded 5.48 million times.

'Lost' was seen by an estimated 13.57 million viewers, 'Heroes' by 5.3 million, meaning more people downloaded 'Heroes' then viewing it.
