Innovation is about change, and media products and services are changing. The processes of production and distribution of media are changing. The ownership and financing of media are changing. The roles of users are changing. And our ideas about media are changing. This book argues that innovation theory provides better tools for media researchers who wish to understand and explain current developments in the media landscape – tools that not only allow them to see completely new things, but also to investigate aspects of new media that would otherwise not be as accessible. The various chapters of the book present selected studies that together illustrate how a more explicit focus on innovation and innovation theory can provide new insights into and generates knowledge about how media innovations develop, the sociocultural conditions of such innovations, the role of technology, and power relations in media developments.
