Communication models of 'one to one', of 'one to many' and of 'many to many' evolved. The term 'virtual' was introduced when digital technologies entered the media arena in the second half of the 20th century and was used for mediated communication facilitated by these digital technologies. Of course, long before the digital technologies were developed, humankind had found many ways to transcend the limits of time and place. But the digital technologies facilitate an entirely different scale of memory, tracing and tracking capabilities, speed of calculation, reproduction and representation possibilities than could be imagined only a few decades ago.
