Namely, legislative limits on campaign finance have been challenged by new forms of digital advertising which are inherently less transparent than their analogue predecessors, thus undermining the existing definitions and restrictions based on specific media types. The safeguards against corruption based on methods for calculating spend and categories for reporting spend on traditional media channels have lost their meaning as political campaigning shifted to the internet. As a result, also the absolute spending limits imposed on broadcasting are becoming less meaningful, while transparency regulations ensuring that citizens are aware of campaign finance and spend are difficult, if not impossible to implement across borders in the digital environment.
