(2013) in accordance with the political economy framework, and examined Amazon through the same intellectual lens in Amazon: Understanding a Global Communication Giant (2020). Brevini also lists sustainable communication, communications systems and climate change, and media reforms in comparative perspective amongst her research interests. Public Service Broadcasting Online: A Comparative European Policy Study of PSB 2.0 (2013) Within Public Service Broadcasting Online, Brevini explores the extent to which the ethos of public service broadcasting has transitioned to the European internet. Brevini considers this issue with reference to Denmark, France, Spain, Italy and the United Kingdom, where Public Service broadcasting has incurred major reforms that have altered its legal and policy-related frameworks. She formulates a normative, democratically-minded framework for ‘public service broadcasting 2.0 (PSB 2.0)’ when considering how public service broadcasting has been expanded and redefined in the new media landscape. Brevini ultimately argues that PSB 2.0 and its reimagining of public service values are crucial in the 21st century – particularly if the internet is to embody the ideals of traditional, non-commercial broadcast television. Amazon: Understanding a Global Communication Giant (2020) Writing with Lukasz Swiatek, Brevini takes a political economy of media approach to understanding Amazon’s role in the global media landscape. She describes Amazon as a "digital lord" that is adapting the principles and practices of medieval feudalism for the Digital Age. Brevini posits that Amazon has built a "digital estate" in its 25 years of operation. Here, consumers are reduced to serfs who must sacrifice their privacy to access the products and services that Amazon offers. Brevini notes that Amazon's rise to prominence has been expedited by a contemporary manifestation of capitalism that favours market concentration and dominance, as well as the absence of regulatory frameworks that could redistribute wealth. Is AI Good for the Planet? (2021) In Is AI Good for the Planet?, Brevini investigates the environmental cost of AI applications. She argues that, while AI is frequently presented as a "magic wand" that will liberate humanity from the climate crisis, technological utopianism can obfuscate the materiality of technology. Accordingly, Brevini highlights four ways in which technologies, machines and infrastructures that use AI can exacerbate global warming. Algorithms require significant computational power to be developed and trained to analyse and categorise data. Substantial amounts of energy and water are required to cool down systems that power AI applications. The minerals required to manufacture AI technologies produce a
