When Facebook launched Instant Articles (IA), some experts said they would be the alternative to all the anxieties of traditional journalism, since the crisis generated by the loss of space for social networks increased the number of closed vehicles, closed print editions, and layoffs of professionals. The reality shows that this did not happen. But the crisis faced by the news industry, and by a still shapeless but potentially powerful news industry, cannot do without all the alternatives capable of recovering the sector s profitability and expanding the access of a layer of the public that never really gained access to the printed newspapers, jumping from word of mouth to radio and TV news stations and, later, quickly, to social network. In this book, I will present an overview of the main functionalities of IA, the problems and unfolding of its implementation process for the journalistic industry, as well as a brief study about its employment by The New York Times and Facebook itself. The book s structure will be divided into three blocks: business models, the Facebook Instant Articles model, and finally mediamorphosis and engagement.
