With the end of ice age, 10 000 years B.C., on the fields of southwest Asia, appeared very first agricultural societies, which marked the end of nomad lifestyle thus creating a very first towns and cities. Creation of civilizations and big social progress came during the early stone age. Invention of steam machine marks a new epoch of human development.

Third industrial revolution was solely technical, during which it came to development of computers, telecommunication and informatization of society. Fourth technological revolution came in 21st century and still lasts. Development of artificial intelligence, smart devices and robotics are its main characteristics. Third and fourth technological(industrial) revolution was marked with the creation of post-industrial society, which is labeled with society informatization. Professional staff is now taking a more significant role. Main blocking factors is not anymore a capital but science workers. A new, intellectual technology appeared, which pushed the usage of computers, informatization and robotization into first plan.
