Book excerpt: Media publishers produce news for a full range of smart devices – including smartphones, tablets and watches. Combining theory and practice, Mobile-First Journalism examines how audiences view, share and engage with journalism on internet-connected devices and through social media platforms. The book examines the interlinked relationship between mobile technology, social media and apps, covering the entire news production process – from generating ideas for visual multimedia news content, to skills in verification and newsgathering, and outputting interactive content on websites, apps and social media platforms. These skills are underpinned with a consideration of ethical and legal concerns involving fake news, online trolling and the economics of mobile journalism. Topics include: understanding how mobile devices, social media platforms and apps are interlinked; making journalistic content more engaging and interactive; advice on how successful news publishers have developed mobile and social media strategies; adopting an approach that is entrepreneurial and user-centered; expert interviews with journalists, academics and software developers; learning key skills to launch and develop news websites, apps and social media outputs. Mobile-First Journalism is essential reading for journalism students and media professionals and of interest to those studying on courses in social and new media.
