The significance of administrative offense law has generally increased significantly in recent years. This trend is particularly pronounced in the field of online media. The penalty provisions in the State Treaty on Broadcasting and Telemedia now include intentional and negligent offenses for broadcasters, listed under 28 categories, as well as 29 additional categories for further intentional acts; some offenses contain multiple variations. Administrative offenses from the Youth Media Protection State Treaty, the Telemedia Act, and other laws are also included. Individual fines can reach amounts of several hundred thousand euros. The legal handbook on administrative offenses in broadcasting and telemedia is now considered a standard reference work. It is tailored to the needs of practice while maintaining scientific rigor.
