Online bingo is the game of bingo (US|UK) played on the Internet. It is estimated that the global gross gaming yield of bingo (excluding the United States) was US$500 million in 2006, and it is forecasted to grow to $1,000 million by 2010.
Unlike balls used in regular bingo halls, online bingo sites use a random number generator. Most bingo halls also offer links to online poker and casino offerings as the patrons are often in the target market. One notable feature of online bingo is the chat functionality. Bingo sites strive to foster a sense of community and interaction between players as this helps customer retention.
One of the earliest known online bingo games, launched in 1996, was a free bingo game called "Bingo Zone". To play, members had to provide demographic information; in turn, members would receive targeted ads based on the demographics provided. Another early pioneer for free online bingo was Uproar, which launched Bingo Blitz in 1998
