NBC's Heroes and ABC's Lost, two sci-fi dramas that ended their runs in 2010, are the TV shows with the most illegal downloads in 2010, according to TorrentFreak.com.

Lost went off the air after wrapping up its sprawling, enigmatic storyline while Heroes was cancelled due to poor ratings. Ironically, Heroes, like the third most-pirated show, Showtime's skin-filled crime drama Dexter, was downloaded by more people who watched it according to the Nielsen ratings. If NBC had been counting illegal downloads instead of legitimate TV viewers, Heroes may still be on the air.

But the question of why so many people downloaded episodes of Heroes and Lost is easy to answer with one look at MrSkin.com.

Heroes boasted some of the hottest babes of the 2000's, like twice-nude Ali Larter and sexy but sadly skinless Kristen Bell and Hayden Panettiere. Lost had more island-stranded beauties than plot twists, including Evangeline Lilly, Maggie Grace, Yoon-jin Kim, Elizabeth Mitchell, Sonya Walger, and Bai Ling.

But why bother with an illegal download when you can see every one of these actresses nude or sexy at MrSkin.com without risking prosecution by the FBI?
