"FHM"'s 100 Sexiest Women was an annual listing compiled by the monthly British men's lifestyle magazine "FHM".  The list was compiled each year by the magazine based on votes from their readers on women whom they believed to the "sexiest".  Each list was first announced by "FHM" through both a dedicated issue of their magazine and a section on their official website, FHM.com.  The first list was published in 1995 and was voted for by a panel of 250 judges; the inaugural winner was the German supermodel Claudia Schiffer.  From 1996 onwards, the poll was instead voted for by the general public, with, at its height, several million votes being cast each year.  Subsequent winners included the Russian tennis player Anna Kournikova, the American actress Halle Berry, and Jennifer Lopez.  At 36 years old, Berry was the oldest woman ever to top the listing, while Lopez was the first to top it more than once.  The list ran every year from 1995 to 2015; by the time "FHM" ceased publication in January 2016, the 100 Sexiest Women list had been compiled 21 times.

Anna Kournikova (named by its author as "Vbs.OnTheFly Created By OnTheFly") was a computer worm written by a 20-year-old Dutch student named Jan de Wit --who called himself 'OnTheFly'-- on February 11, 2001.  It was designed to trick email users into opening a mail message purportedly containing a picture of the tennis player Anna Kournikova, while actually hiding a malicious program.  The worm arrives in an email with the subject line "Here you have, ;0)" and an attached file called AnnaKournikova.jpg.vbs.  When launched under Microsoft Windows the file does not display a picture of Anna Kournikova but launches a viral Visual Basic Script that forwards itself to everybody in the Microsoft Outlook address book of the victim.
