The Internet has profoundly changed our lives and become very important for the German economy. This study highlights the variety and importance of the Internet industry in Germany. In addition to the analyses made previously (in 2013), there is a considerably stronger focus on topics such as market dynamics, competition, profitability, maturity, and M&A activities in the individual segments in this study. This year’s study, “The German Internet Industry 2016 – 2019”, builds on the model introduced in the first publication (2009), in which the Internet industry was portrayed in four layers. The model has been adapted slightly to reflect the dynamism of the market.
