Top-selling movies (PN)~ The collection title for movies that are in the top N% of sales. Torrent ~ A method of making data available for download over the internet where the recipient of data is expected to make the data available to others for download from their PC rather than all users downloading from a central server. Typically much of the data is bootleg software audio and video. Because the data is distributed from multiple computers all over the place rather than a central point it is difficult to police.
