Social media have become, in the current context of the digital explosion, alternative media to traditional media which, until the end of the 20th century, conquered the public space and induced a fixed tradition in terms of information consumption mode. The paper newspaper to read each morning, the radio to listen and the television to watch were inextricably linked to the life of the human beings. One spoke then about the habitus of the consumer. But with the dazzling technological revolution, there has been the alteration of this mystery of the classic media, which is now strongly challenged by social networks that create and reinforce the social link as well as a dynamic of plural interactions, justified by the fast diffusion and the easy access to information. The author of this book, in a style of observation that is both analytical and comparative, proposes a professional and scientific reflection on the conflict or interdependence of social media and traditional media. This is based on notes of interviews given by media professionals and communication experts from Benin, Africa and Europe.
