There is no doubt that human beings have been gambling for hundreds of years, and there is ample evidence that sports gambling can be traced back at least as far as the Roman arenas where an enthusiastic crowd would often gamble on the outcome of both physical combat and chariot and horse races. Even what we now call casino gambling existed in the era of the Greek and Roman empires, and many of our traditional casino gambling games have their roots in this period of our history. What has changed is the influence of technology on our gambling activities. The first penny slot machines for instance started to appear in the Victorian era, mostly as part of the entertainment provided on seaside piers when holidays at the beach started to attract a wider audience. In the latter part of the twentieth century the complexity of the slots gambling machines began to increase rapidly and they became a regular fixture in almost every pub and club so that slots gambling was available almost everywhere on a regular basis. Next in the development of the casino gambling scene was of course the introduction of online sports gambling sites most of which also featured casino gambling games on the same site. Most people would agree that the associated casino software needed to operate an online casino gambling site has probably been the biggest single factor in the massive expansion of slots gambling. Without the space constraints of real casinos or arcades, the online casino gambling sites have been able to take advantage of modern software technology to such an extent that there are now hundreds of different slots gambling games available to anyone who has a computer, laptop or tablet at home. They are even available on our mobile phones. Some would now argue that online slots gambling is now the biggest gambling activity there has ever been.
