Digital Currents


Book Description

Rena Bivens takes the reader inside TV newsrooms to explore how news organisations are responding to the paradigmatic shifts in media and communication practices.




Digital Currents


Book Description

Digital Currents explores the growing impact of digital technologies on aesthetic experience and examines the major changes taking place in the role of the artist as social communicator. Margot Lovejoy recounts the early histories of electronic media for art making - video, computer, the internet - in this richly illustrated book. She provides a context for the works of major artists in each media, describes their projects, and discusses the issues and theoretical implications of each to create a foundation for understanding this developing field. Digital Currents fills a major gap in our understanding of the relationship between art and technology, and the exciting new cultural conditions we are experiencing. It will be ideal reading for students taking courses in digital art, and also for anyone seeking to understand these new creative forms.




News Discourse and Digital Currents


Book Description

In recent years, journalistic practices have undergone a radical change due to the increasing pressure of new digital media on the professional practice. The ever-growing development of new technologies and the ceaseless fluctuation of social practices have challenged some of the traditional genres found in these professional contexts. On the basis of these premises, this book investigates a particular genre found in the context of TV newscasts. The genre under investigation is that of news tickers (or crawlers), that is, the graphic elements that scroll at the bottom of the screen during newscasts. The book introduces readers to this under-researched genre through a year-long collection of the news tickers displayed on BBC World News. Thanks to a corpus-based genre analysis, the generic status of news tickers is better defined by highlighting the presence of given strategies of marketization. Additionally, this volume investigates if news tickers can be seen as a mixed (sub-)genre that interdiscursively combines traditional linguistic elements of headlines and lead paragraphs to achieve, from a (Critical) Genre Analysis point of view, a specific private intention in the context of the BBC.
