The online casino industry has grown rapidly over the course of the last ten years. While at the end of the 20th century there were only several dozen online casinos available to gamblers, over the last ten years their numbers have grown exponentially and today gamblers have a choice of over a thousand online casinos.
Land-based casinos, especially in the US, have always promoted themselves as fun-filled places where men, and later on also women, can gamble and have a good time and if they gamble enough their hotel rooms will be comped by the casino to encourage high rollers to come and wager at their establishment.
In Las Vegas, Nevada the casinos have realized, soon after their establishment that if they want to attract the men to gamble they need to provide entertainment to women. Free drinks were offered to the ladies waiting for their husbands or lovers who were at the tables playing.
When slot machines were introduced the game mainly drew bored women who had nothing better to do in the casino. The casino owners have quickly identified an additional source of income and started heavily promoting the game to women.
