Beer pong, also known as Beirut, is a drinking game in which players throw a ping pong ball across a table with the intent of landing the ball in a cup of beer on the other end. The game typically consists of two two-to-four-player teams and multiple cups set up, in triangle formation, on each side. There are no official rules and rules may vary widely, though usually there are six or ten plastic cups arranged in a triangle on each side. Each team then takes turns attempting to shoot ping pong balls into the opponent's cups. If a ball lands in a cup, then the contents of that cup are consumed by the other team, and the cup is either placed aside or reinserted into the triangle. If the cup is reinserted and the other team knocks the cup over, it is removed. If the opposing team throws the ball into an empty cup, they must consume the contents of one of their cups. The first side to eliminate all of the opponent's cups is the winner.

The order of play varies—both players on one team shoot followed by both players on the other team, or players on opposite teams can alternate back and forth.

Beer is the world's most widely consumedalcoholic beverage; it is the third-most popular drink overall, after water and tea. It is thought by some to be the oldest fermented beverage. Beer is produced by the saccharification of starch and fermentation of the resulting sugar. The starch and saccharification enzymes are often derived from malted cereal grains, most commonly malted barley and malted wheat. Unmalted maize (US: corn) and rice are widely used adjuncts to lighten the flavor and because of their lower cost. The preparation of beer is called brewing. Most beer is flavoured with hops, which add bitterness and act as a natural preservative, though other flavourings such as herbs or fruit may occasionally be included. Some of humanity's earliest known writings refer to the production and distribution of beer: the Code of Hammurabi included laws regulating beer and beer parlours, and "The Hymn to Ninkasi", a prayer to the Mesopotamian goddess of beer, served as both a prayer and as a method of remembering the recipe for beer in a culture with few literate people. Today, the brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries.

Pong (marketed as PONG) is one of the earliest arcade video games, and is a tennis sports game featuring simple two-dimensional graphics. While other arcade video games such as Computer Space came before it, Pong was one of the first video games to reach mainstream popularity. The aim is to defeat the opponent in a simulated table tennis game by earning a higher score. The game was originally manufactured by Atari Incorporated (Atari), who released it in 1972. Allan Alcorn created Pong as a training exercise assigned to him by Atari co-founder Nolan Bushnell. Bushnell based the idea on an electronic ping-pong game included in the Magnavox Odyssey, which later resulted in a lawsuit against Atari. Surprised by the quality of Alcorn's work, Atari decided to manufacture the game.

Pong quickly became a success and is the first commercially successful video game, which led to the start of the video game industry. Soon after its release, several companies began producing games that copied Pong's gameplay, and eventually released new types of games. As a result, Atari encouraged its staff to produce more innovative games. The company released several sequels that built upon the original's gameplay by adding new features. During the 1975 Christmas season, Atari released a home version of Pong exclusively through Sears retail stores. It was also a commercial success and led to numerous copies. The game has been remade on numerous home and portable platforms following its release. Pong has been referenced and parodied in multiple television shows and video games, and has been a part of several video game and cultural exhibitions.
