One of the most popular definitions used in Poland (does not apply to government documents and translations of EU documents):

„Społeczeństwo informacyjne to społeczeństwo, które nie tylko posiada rozwinięte środki przetwarzania informacji i komunikowania, lecz środki te są podstawą tworzenia dochodu narodowego i dostarczają źródła utrzymania większości społeczeństwa".

“The information society is a society which not only has developed means of information processing and communication, but these means are the basis for creating a national income and provide a source of income for the majority of society".

*Goban-Klas T, Sienkiewicz P.: Społeczeństwo informacyjne: szanse, zagrożenia, wyzwania, Wydawnictwo Fundacji Postępu Telekomunikacji, Kraków 1999

The term "information society" has been in use since the 1970s but there is indeed no universally accepted definition. Notwithstanding, Webster (2002) made out five analytically separate definitional criteria (a) technological, (b) economic, (c) occupational, (d) spatial, and (e) cultural. That said, many definitions draw from a mix of technological, economic, and occupational perspectives. Based on Porat (1977), for example, the OECD has defined the information society as a society where more than half of the GNP is produced and more than half of the employees are active in the information economy.

Thank you for your answer. Of course I am aware of that. However, I am primarily interested in definitions that build social awareness thanks to their local / regional popularity
