It seems that the history of the creation of technological products by Mark Zuckerberg (Mark Zuckerberg) is noticeably longer than previously believed by the public. Founder and CEO Facebook, living in New York at the age of 10-12 years, created a chat service for his family and his father's dental practice.

"My father's dental office was in touch with our house," Mr. Zuckerberg noted in a recent podcast with entrepreneur and early Facebook investor Reid Hoffman (Reid Hoffman). - Dentists and hygienists needed to exchange information about patients. So I created a system with which my father could communicate with colleagues in various offices, and also be in touch with me and my sisters on the floor above - I called her ZuckNet.

In fact it was our small network, inside the Zuckerberg house, and it was fun.

It was something of a forerunner of various ideas related to social software, which I researched over time, but very, very early. And soon, of course, there was AOL Instant Messenger, and everyone started using it ".

The irony is that AOL was ultimately also driven out of the market, already another creation of Mark Zuckerberg: Facebook. Currently, the largest social network in the world is developing two instant messengers, Facebook Messenger and WhatsApp, each of which has more than 1.2 billion active users around the world.
