For advertisers and news publishers, brand sponsored content has offered attractive solutions to problems of ad-avoidance and financing journalism. This book is an investigation into the practices, possibilities and problems of sponsored editorial content across various national and regional contexts.Sponsored editorial content is material with similar qualities and format to content that is typically published on a platform or by a content provider, but which is paid for by a third party. Brand sponsored content may not be the remedy for ad-dependent media some advocates predicted but its expansion has impacted on the organisation, practices and identities of journalism in profound and far-reaching ways. This book explores the features and implications of content that blends, merges and disguises material that is sponsored with material that is or appears to be independent editorial.The chapters range across countries and regions from China and Israel to Europe and North America. Following a general introduction, authors address political and commercial sponsorship across production, content and audience research, developing and combining these in innovative ways to advance the study of paid-for content in contemporary digital journalism. This book was originally published as a special issue of the journal Digital Journalism.
