The term digital age has no formal definition, but it generally refers to a time when a substantial amount of information is captured and stored in digital form. This information is shared via the Internet or other digital channels. The digital age has arrived at different times in different parts of the world. In the United States and Europe, it can be said to have started sometime in the mid-1990s, while some developing countries are not yet in the digital age. Personally, I see three turning points for the lives of ordinary users. The first was the emergence of public-facing websites; by this I mean, for example, news servers, shop pages, Internet banking, travel agency catalogues, etc. This was the moment when the ordinary user realised that a computer with the Internet could be useful to him, even if he did not know the principles of its operation and could not program it. The second was the increase in the availability of Internet access to the public via fixed telephone lines and the gradual decline in its price. The third milestone is the massive emergence of mobile internet, which went hand in hand with the growing popularity of social and communication networks such as Facebook.
