Before 1800's- online casino obviously not in existence yet but ancient European civilizations begin to game within their community. They gamble on things like the weather and try to predict random events. 1900's- the 1900's saw technological advancements that would eventually lead to the type of technology needed to establish the online casino. Where horse and buggy were slowly being replaced for cars, technicians were beginning to realize the potential of technological machinery and the invention of computer like systems. 1980's and beyond- the 1980's saw the first IBM PC and the first of computers as we know them today. We should not forget that there are evolutions happening to the computer on a daily basis and the end result of all these changed is still unknown. Technological advances and advanced computer simulacrum made the modern day online casino that players are used to seeing. The technological advances made the necessary machinery that would allow for people to game against each other and to game against the computer. 

The online casino became a commodity when the random number generator came fully into effect. The random number generator became the dealer of the online casino that would ensure that random numbers were being produced and that the player was experiencing the same level of fair gaming as was guaranteed to him/her in the land based casinos. It was in 1994 that the Antiguan government passed a law that allowed for the basing of the online casino to be in Antigua's borders. This was referred to as the Free Trade and Processing Zone and this is when many of the notorious names in the online casino world were birthed. After the conventional online casino launched been over exercised, online casino sites began to put in other features that would make them indispensable. Some of these include the feature of live dealers, bingo options, and poker room affiliate links and of course, affiliated programs that would make networking possible for the online casino. In 1995, Crypto logic was developed and this online casino technology became the first generation of what was next to follow.

The first online casino to actually accept real money wagers was Intercasino and this took place in the year of 1996. In 1998 there were finally accumulated revenue reports that could position the online casino industry in the global market. The 1998 reports showed that the online casino industry had generated around $830 million in that year. Once this amount was reported, as can be expected, many new investors began to either make new online casinos or to invest into already existing ones. The advertising world, especially online advertising companies, also started to emphasize the potential of this market and through their marketing campaigns; the online casino world is where it is at right now.

Casino originally, a public hall for music and dancing; by the second half of the 19th century, the term meant essentially a collection of gaming or gambling rooms. The classic example of a casino, and for long the world's best-known one, which was opened in 1861. The casino has long been a major source of income for the principality of Monaco. The 20th-century casino, which may also be called a gambling, or gaming, house or club, is a place where gamblers can risk their money against a common gambler, called the banker, or the house. Casinos have almost a uniform character throughout the world. In Europe and South America, they are permitted at many or most holiday resorts and not elsewhere. In the United Kingdom, licensed and supervised gambling clubs, mainly in London, have operated since 1960. Club membership is required and easily obtainable. The government in France, which boasts the majority of European casinos, also regulates casinos. In the United States, legal casinos were long operated only in Las Vegas and other locations in Nevada, where various forms of commercialized gambling were permitted. The economy of Las Vegas is almost entirely dependent on the large, luxurious casinos that have operated there since the late 1940s. 

Casino gambling was introduced in Atlantic City, N.J., in 1978, and from the 1980s casinos also began appearing on various American Indian reservations, which are not subject to state antigambling statutes. Other legal casinos are located on riverboats; in Deadwood, S.D.; and by special license in Puerto Rico. A general expansion of casino gambling was underway in the United States by the last decade of the 20th century. In South America, there are casinos in Argentina, Colombia, and Ecuador. The casino at Havana, Cuba, was closed after the revolution in 1959. The casino typically accepts all bets made by its patrons within a limit established so that a patron cannot win more than the casino can afford to pay. Every game offered gives the casino a mathematical expectancy of winning, and it is unlikely that a casino might lose money on its games, even for one day. Because of this virtual assurance of gross profit, casinos regularly offer big bettors extravagant inducements in the form of free spectacular entertainment, transportation, and elegant living quarters. Even lesser bettors are offered reduced-fare transportation, hotel rooms, free drinks and cigarettes while gambling, and other inducements. Such promotional expenses may exceed profits and cause a net loss over the year.

Of the games played regularly at casinos, roulette is found throughout the world, being a principal gambling game in France, where the casinos reduce their advantage to less than 1 percent to entice big bettors. In the America, roulette appeals more to small bettors, and the casinos take a larger percentage. Crap shooting attracts the big bettors in American casinos, most of which demand an advantage no greater than 1.4 percent, some only 1 percent or less. Slot machines and (from the 1980s) video poker machines are the economic mainstay of American casinos, the income resulting from high volume, rapid play at sums ranging from five cents to one dollar, and the ability to adjust machines for any desired profit.
