The barriers to regulating the online world: Insights from UK debates on online political advertising

Online political advertising has grown rapidly over the last two decades and played an important role in campaigns and elections. Arising with it are concerns around issues such as data privacy and transparency, which have sparked calls for regulation. Whilst change has begun to be implemented, in many contexts moves to regulate online political advertising have been limited. In this article, we explore one such case, asking whether attempts to regulate have been hindered by the particular characteristics of digital technology or by wider political factors. Presenting new interview data examining the experiences and perceptions of regulators, policy makers, civil servants, civil society groups and academics in the United Kingdom, we distil three barriers: political reticence, logistical challenges and conflicting policy proposals. Our findings suggest that efforts to regulate online phenomena need to apply a media and politics-centric lens, considering how the technological traits of digital media and political factors can affect efforts to regulate.
