For the ninth time, the Graz University of Technology has carried out a survey amongst its freshmen in order to find out their preferences and habits according to the use of modern IT- and Web- technologies. Besides the remarkable long-term changes in regards to the ownership of technology, the results of this year ́s (2015) survey yielded a sensation. The instant messaging client for smartphones “WhatsApp” has superseded e-mailing from its leading position of being the preferred communication media. E-mailing was displaced on second place for the first time after nine years of survey. A clear trend can be stated in regards to communication media. The influence of WhatsApp on other communication behavior, notably e-mail and SMS, as well as the lasting rise of WhatsApp itself are special focuses of this paper.
