While online selling had already been around for centuries, the Holomarket was an important improvement of the philosophy of selling. Thanks to the infrastructure that was already in place since the propagation of the Neural Interface, sellers could give their potential customers the opportunity to directly test their products an all their features in virtual space (sometimes projected over real space), before making decision of purchase. Of course only physical objects, such as houses, cars or androids could be advertised with holomodels, since it would make no immediate difference to the user if he or she was reading a real or virtual book.
