"2017 was marred by the assassination, in Malta, of the investigative journalist Daphne Caruana Galizia, an event which represented the darkest hour for media freedom and media pluralism in the European Union since the 2015 Charlie Hebdo massacre in France. This crime has profoundly shaken Europe and has had an impact on its image as a bastion of human rights and democratic values. Publishers continued to face significant economic pressures, and 2017 confirmed the decline in the revenues of the press sector and of many local and community newspapers across Europe, a worldwide trend signalling continued job losses in the sector and the lower viability of the media business as organisations struggle to find sustainable business models in the face of digital transformation. The spread of online disinformation and hate speech, including concerns about their impact on elections and referenda in 2016, represented major areas of debate during 2017. States, international institutions, and private enterprises have discussed or adopted measures – both legislative and non-legislative – to address these phenomena, and several of these measures have, in turn, raised concerns about their impact on the freedom of expression and respect for the rule of law. Due to the aforementioned concerns with regard to the economic difficulties faced by publishers, as well as online hate speech and disinformation, 2017 was noteworthy for an increased interest in the analysis of the influence of major online platforms in both public debate and public opinion. Queries over accountability, transparency and the overall effect on democracy in relation to the digital platforms have escalated. In 2017, several stakeholders expressed concerns about such platforms’ use of machine learning and algorithms in personalising news feeds, as well as their use of the end-users’ data for targeted advertising purposes."
