Voyeurism is the sexual interest in or practice of spying on people engaged in intimate behaviors, such as undressing, sexual activity, or other actions usually considered to be of a private nature.

The principal characteristic of voyeurism is that the voyeur does not normally relate directly with the subject of his/her interest, who is often unaware of being observed. Voyeurism may involve the making of a secret photograph or video of the subject during an intimate activity. When the interest in a particular subject is obsessive, the behavior may be described as stalking.

However, in today's society the concept of voyeurism has evolved, especially in popular culture. Non-pornographic reality television programs such as Survivor and The Real World, are prime examples of voyeurism, where viewers (the voyeur) are granted an intimate interaction with a subject group or individual. Although not necessarily "voyeurism" in its original definition, as individuals in these given situations are aware of their audience, the concept behind "reality TV" is to allow unscripted social interaction with limited outside interference or influence. As such, the term still maintains its sexual connotations.
