People turn to local media for information during crises such as the coronavirus pandemic (COVID-19). What factors impact media consumers’ decisions about which local television news broadcast to watch? This study argues that media consumers infer the partisanship of local television affiliates — judging local Fox and NBC news broadcasts to be right and left slanted, respectively, based on their perceived associations with Fox News and MSNBC. Using the results from a representative survey of Americans (N = 5,461), the study demonstrates that local Fox and NBC viewers are significantly more likely to watch Fox News or MSNBC. As a result, watching local Fox is associated with less coronavirus risk because media consumers choose local Fox believing that it will align with their existing conservative views. This study demonstrates the importance of the perceptions of local news partisanship in influencing the consumption of critically important local crisis news.

We now have more information from more sources than ever before, but the free flow of information has also opened the doors to misinformation, fake news, propaganda, and manipulation of information (Berduygina et al., 2019). Some researchers argue that media is profit-driven and promotes advertisers and elites, ignores the audience need for accurate and objective information (Akhavan-Majid & Wolf, 1991). Jacob L. Nelson writes in his latest book, “Imagined Audiences: How Journalists Perceive and Pursue the Public,” that it is time to shift the focus from profit to audience. He claims that this shift would help news media regain financial stability and that journalists should work alongside the audience if they want to recover public trust. Nelson’s book was published in 2021 by Oxford University Press. It has seven chapters and in each of the chapters, the author explores different questions, such as: how do journalists conceptualize their audiences? Who gets included in these conceptualizations and who is left out? And most importantly, how aligned are journalist’s ‘imagined’ audiences with the real ones? Nelson explores these issues through an ethnographic study of the Chicago Tribune and City Bureau newspapers, along with the media consulting firm Hearken. Throughout the book, he focuses on the relationship between journalists and the audiences during a time when the newspaper industry in America is losing revenue, cutting jobs, and dealing with the proliferation of fake news. In the first chapter, Nelson investigates how journalists today are trying to understand their readers and working to strengthen their relationship. The author writes that journalism practitioners usually conceptualize audience as faceless or nameless subjects who independently watch, read, or listen to the news. Journalists know of the audience’s existence but intentionally choose not to think about them, thus ignoring Book Review
我们现在比以往任何时候都有更多的信息来源，但信息的自由流动也为错误信息、假新闻、宣传和信息操纵打开了大门(Berduygina et al.， 2019)。一些研究人员认为，媒体是逐利的，宣传广告商和精英，忽视了受众对准确客观信息的需求(Akhavan-Majid & Wolf, 1991)。雅各布·纳尔逊(Jacob L. Nelson)在他的新书《想象中的受众:记者如何感知和追求公众》中写道，现在是时候把关注的焦点从利润转向受众了。他声称，这种转变将有助于新闻媒体重新获得财务稳定，如果记者想要恢复公众的信任，他们应该与观众一起工作。纳尔逊的书于2021年由牛津大学出版社出版。它有七章，在每一章中，作者探讨了不同的问题，如:记者如何概念化他们的受众?谁被包括在这些概念中，谁被遗漏了?最重要的是，记者的“想象”受众与真实受众的一致性如何?尼尔森与媒体咨询公司Hearken合作，通过对《芝加哥论坛报》(Chicago Tribune)和《市政局》(City Bureau)报纸的人种学研究，探讨了这些问题。在整本书中，他关注的是在美国报业收入下降、裁员以及应对假新闻泛滥之际，记者与受众之间的关系。在第一章中，尼尔森调查了今天的记者如何试图理解他们的读者，并努力加强他们的关系。作者写道，新闻从业者通常将受众定义为独立观看、阅读或收听新闻的无名主体。记者知道读者的存在，但故意选择不去想他们，从而忽略了书评

This study integrates the Spiral of Silence and Uses and Gratifications theories to examine the willingness of university students to express on Twitter their opinions about a controversial issue, women serving as judges in Kuwait and Egypt. The analysis of a survey of 640 respondents showed that they used Twitter for information seeking, opinion formation, opinion reinforcement, and social utility in discussions, and for its democratizing capability. Democratization was the only motive to predict the expression of opinion online. When the Kuwaiti and Egyptian samples were analyzed separately, the democratization motive predicted opinion expression for the Kuwaiti students but not for the Egyptian students. Interaction effects between motivations and size of the respondent's social network on Twitter were found to predict the online expression of opinion. For example, the variable assessing the size of a respondent's social network interacted with information seeking motivation and also with opinion reinforcement to predict opinion expression online.

Fox News is one of the most popular news sources in the United States. Yet, there are those who reject the idea that Fox should be considered a news source in the first place, claiming it should be considered something more akin to propaganda. This article uses the ambiguity surrounding Fox News’ classification as an opportunity to explore how news sources get defined and categorized within journalism research and practice. It discusses three approaches that can be utilized to understand and categorize partisan media—producer-focused, audience-focused, and critical/normative. It explores the benefits and limitations of these perspectives and the need for scholarly inquiry that transverses and synthesizes them. We argue that an increasingly variegated news landscape calls for scholars to develop a richer vocabulary for distinguishing key features of partisan news outlets and greater reflexivity in research design that acknowledges the challenges inherent in translating meaning and values between producers, audiences, and scholars.

Matt Taibbi's “Hate, Inc.: Why Today's Media Makes Us Despise Each Other” (OR Books 2021) might make you angry, but it will make you think. Taibbi's takedown of commercial media, now updated in a post-election edition, offers a striking critique of the news media's slow but steady slide toward polarization “…skewed by a toxic mix of political and financial considerations” (20). Taibbi convincingly argues, using both historical and modern examples along with personal experience, that the press sells people on a simplified worldview where the two political parties are in a constant and perpetual conflict about everything. While Taibbi does offer some advice for independent-minded journalists seeking to navigate the current media landscape, audiences are left with little in the way of solutions, other than to stop reading (and watching) the news.

Sinclair Broadcast Group owns over 170 US television stations. Using agenda setting and agenda cutting as a theoretical lens, this study quantifies the effect of Sinclair ownership by analyzing over 340,000 news stories from six station websites over 4 years through time series modeling. Sinclair ownership negatively changes total news stories output for all six outlets. The percentage of news that is local continues to decline at all but one website. This decline predates Sinclair but continues to date. Stations appear to rely on syndicated (a.k.a., reposted) coverage more than ever, but this again predates Sinclair. An agenda cutting effect was observed; Sinclair cut party politics coverage at all six stations.

During the early weeks of the U.S. COVID-19 pandemic, society was battling an infodemic–defined as a “tsunami” of online misinformation. Through the lens of mediatization theory, this article examines 800,000 tweets to understand social media information and misinformation related to the COVID-19. Through multi-layered analysis, this article details prominent key words discussed on Twitter connected to pandemic trending hashtags in early-to-mid March 2020: #Covid19 and #Coronavirus. The most prominent word themes included: novelty of this virus and associated uncertainty and the spread of misinformation; severity and widespread reach of the virus; call for collective action; and expectations relative to government action. The article explains these findings through mediatization theory, applying how technology influences social media discussions.

Social media use is essential for success in today's television news industry. Broadcast journalists use social media platforms to gather and disseminate news in more efficient ways. Broadcasters are also using social media to engage with news consumers in innovative ways. This study employs a mixed-method approach to better understand how social media impacts broadcast journalists’ routines and values and explores the role of gender in broadcasters’ social media strategies. Qualitative in-depth interviews with top broadcast journalists and a social media discourse analysis of their Twitter pages produces this study's findings. Findings suggest that in many television newsrooms social media have become more important than traditional platforms like evening newscasts, and social media metrics are being used to gauge journalists’ success. Additionally, women broadcasters are disadvantaged by the current social media practices in many newsrooms. Implications are discussed.
