A dead pool, also known as a death pool, is a game of prediction which involves guessing when someone will die. Sometimes it is a bet where money is involved. 
- In the early 20th century, death pools were popular in dangerous sports such as motorsport, for example the first edition of the Indianapolis 500.
A typical modern dead pool might have players pick out celebrities who they think will die within the year. Most games start on January 1, and run for 12 months although there are some variations on game length and timing.
In 2000, website Fucked Company claimed to be a "dot-com dead pool" which invited users to predict the next Internet startups to fail during that era's dot com bust. The site itself folded in 2007 after a long history as a target for strategic lawsuits against public participation by companies.
Application in contemporary society
The concept and success strategies are also detailed in a (previously) annual guide called The Dead Pool, written by KQRS-FM radio personality Mike Gelfand and author Mike Wilkinson. KQRS-FM in Minneapolis/St. Paul, Minnesota also does an annual on air dead pool contest, where show hosts and listeners will attempt to pick which celebrity will die in that calendar year.
In his AP news article "Some say death pools are in poor taste", (which brought national attention to The Old Blue Eyes Celebrity Death Watch) author Matt Sedensky writes, "Players scour newspapers and Web sites for news on celebrities' health; they rely on tips from insiders; and they consider a public figure's lifestyle, absence of recent appearances and rumors of illness"..
