As people living in the turn of the century, we have this amazing opportunity to observe the extremely fast pace of civilization development. Nowadays, in order to notice the enormous changes in the world, we no longer have to ask parents or grandparents what it was "in their time". It is enough to go back even 10 years to smile with pity and nostalgia, remembering what life, communication and even everyday electronic equipment looked like then. The discussion about advantages and disadvantages of such a state of affairs is a material for separate series of articles, or even an entire book, so we will not deal with it now. But the fact is, that such changes force changes. Changes in running a business, marketing, acquiring customers, because whoever stands still, he is going back.
