The other regulatory challenge is determining the scope of regulation in relation to the range of actors in the media ecosystem. With the growth of UGC activity within the public sphere, how broadly should the regulatory net extend? The Audiovisual Media Services Directive has confined its reach to commercial activities through the definition of an “audiovisual media service” (and there would be constitutional limits on regulating non-economic activities).In the dynamic media ecosystem, it is likely that the question about the reach of the regulatory net will change over time and for different purposes. One approach may be to ask whether the service offered has become or is likely to become “…a „mainstream means of media consumption for many people.”
