Power Hour or 21 for 21 is a drinking event where player(s) drink a specified number of alcohol shots within one hour. Variants include one shot of beer every minute for an hour or 10 shots within one hour. In the USA, a power hour event is often associated with a person's 21st birthday when they reach the legal drinking age.

Consequences

Players may have difficulty completing the specified number of drinks as the rate of consumption can raise their blood alcohol content to high levels. The rate of alcohol consumption makes the players intoxicated within a short period of time.

Trademark controversy

In 2010, Power Hour LLC, who markets a DVD game named "Power Hour", registered a trademark of the same name and soon after began sending cease-and-desist orders to Ali Spagnola, a musician who had released an album also titled Power Hour. Spagnola announced her intentions to fight the claims, and an intellectual-property professor from the University of Pittsburgh stated that "if 'Power Hour' is a generic description of 'a drinking game that involves drinking a shot of alcohol each minute for an hour,' then Power Hour LLC can't have any trademark rights at all." In January 2013, courts ruled in Spagnola's favor.

Alternate Meanings

The term "Power Hour" has also been used in television to refer to back-to-back showings of half-hour TV shows, particularly action-oriented children's programming.
