A notable exception is attention to the topics of Islam and Ukraine. However, our data reveal that historically geographical penetration of “” proceeded from the regions considered the most modernized to those considered the most traditional. This finding supports the theory of uneven modernization, but it also shows that digital inequality is subject to change with time.
