An introduction to each chapter before the core of the significant innovation will be an analysis of the general situation. The purpose of this thesis is to analyze the innovations of the past 6 years that have significantly contributed to the improvement of communication between citizens and institutions. Although the aim of this paper is to analyze innovations in the public sector, innovations in the real sector are not less important, so I will partialy analyzed them too. The main hypothesis of the thesis relates to the question of whether the significant innovations we will analyze are really significant and have they contributed to the improvement of the system and facilitated the daily use of citizens.
