Today children spend their childhood completely different than their parents in their childhood.
The main causes for differences are advances in digital technologies, especially with respect to
mobile technology. Therefore, these new technologies are increasingly often also the subject of
corresponding research; particularly the aspects of online habits, interests, opinions, emotions and
parent-imposed usage controls. Within this context, we conducted a thorough review and
comparative analysis of nine such researches conducted in EU and OECD countries between the
years 2011 and 2020. We were particularly interested in the research content and its change over
time, as well as in the content that was not covered, but should be included. We concluded that the
most commonly researched topics were access to internet, risks, opportunities, online activities and
role of parents. These categories have remained the same in the studied period. In addition, we also
found a certain lack in research covering online games and latest technologies, such as augmented
reality or virtual reality.
