The casino has always been associated with glitz and glamor, celebrity and enthusiasm.  It has long been a target for the rich and famous, high rollers who lure big fortunes against casinos.  They are also often used to generate hoarding communities around the world, as huge revenue is generated and businesses and jobs that arise from their sheer presence.  However, now in the 21st century, the casino has undergone a significant electronic change.  The Internet has been used as a platform for all types of makeovers and facelifts.  Due to its huge size and worldwide audience, the Internet has become a playground to recreate new and old ideas.  Online auctions have become huge as the e-commerce industry, but few can rival the huge financial and market gains generated by online casinos.  Although similar to their real-life counterparts, the online version of the casino has been quick to help others benefit from their success.

    The most prominent subsidiary business stemming from the online casino industry is affiliate marketing.  Affiliate market is extremely important for businesses of all sizes due to the need to reach a large audience.  Affiliates allow casinos from around the world to reach vast audiences, more affiliates who can make the most of their visibility on a site.  From a casino point of view this marketing asset is better than the fact that they do not have to pay any fees for the pleasure of this advertising space.  Their brand can be spread across the world's largest market and is free.  Unlike more expensive activities, instead of advertising on hoardings, magazines or sponsorship events, there is no required payment up front.  This is because the affiliate program works on a reward basis;  The casino supplies rewards to affiliate customers.

    However this system of marketing does not work only in favor of huge casinos.  Affiliates are rewarded for their share in the business equation, with casinos offering up to 35% for privileges.  Unlike other affiliate programs, most casinos will provide a percentage of a player's revenue for their entire lifetime, rather than a one-month transaction or a few months.  Therefore the program works efficiently in providing both parties with what they need.  Affiliates earn their money by supplying to customers, while casinos profit from new customs and all possible income.  To attract as much as possible for each individual, a class is placed on each affiliate to generate more revenue for themselves.  But this in turn also favors casinos, making affiliate programs one of the most profitable and advertising systems.
