1. Externalization: students more and more shift from using internal to external services, e.g. from the university
library catalogue to Google Scholar when searching for literature
2. Concentration:
• The usage patterns are consolidating and already often used media are even used even more, on the other
hand little used media are used even less.
• Some big players are drawing over the usage from other services, e.g. the usage of Instant Messenger
software is replaced by the chat feature of Facebook
