An administrator of EliteTorrents.org, a peer-to-peer network focused on distributing movies, has been sentenced to 18 months in prison.
Daniel Dove, 26, formerly of Virginia, was also fined $20,000 (£11,300), the US Department of Justice has said.
Dove had been found guilty of conspiracy and felony copyright infringement on June 26.
Before the website closed in May 2005, EliteTorrents.org offered movies to other P-to-P users, often before they reached cinemas, the DOJ said.
Dove was an administrator of a small group of EliteTorrents members known as "uploaders", who were responsible for supplying pirated content to the group, the DOJ said.
Dove recruited members who had very high-speed Internet connections to become uploaders, and operated a high-speed server.
His conviction is the eighth resulting from Operation D-Elite, a US federal crackdown against the illegal distribution of movies, software, games and music over P-to-P networks using BitTorrent file-sharing technology.
The EliteTorrents P-to-P network at one point had more than 125,000 members and shared 700 movies. The network also offered pirated software, video games and music to its members, the DOJ said.
