In the current media ecology, audiences are constantly tempted by many types of content scattered across connected platforms. Since cultural goods consumption is a practice that now takes place in a constant flow across different platforms, news and documentary narratives must take advantage of the malleability of digital language to engage citizens. Narratives change according to the dominant intellectual technology of the time. In this way, oral narratives are different from printed media and the transmedia storytelling that digital communication promotes. DocuMedia: Social Media Journalism is a series of interactive documentaries developed in Argentina at Rosario National University to bring users new narratives of local interest around journalistic research topics. DocuMedia is the result of crossing documentary, investigative journalism, and data journalism techniques with a focus on users’ participation and the expansion of narrative plots. DocuMedia projects are an example of location-based storytelling, that is, a narrative that stems from hyperlocal space and place and operates as a device of constant social reconstruction. In these experiences, memory is understood as the meanings that citizens share and, above all, develop as a social practice, through which identity is expressed and shaped. The fifth DocuMedia project, Women for Sale: Human Trafficking with Sexual Exploitation in Argentina, was launched in 2015 and took on the challenge of making the leap from multimedia journalism to transmedia journalism. The transmedia framework for Women for Sale included a webdoc, or interactive multimedia documentary, a serial graphic novel of five episodes (print and digital version), posters on the street with augmented reality interaction, short videos projected on indoor and outdoor LED screens, television spots, a collaborative map, a television documentary, mobisodes, the e-book What Happens Next? Contributions and Challenges for the Reconstruction of Rights of Trafficking and Sexual Exploitation Victims, and a social media strategy designed to share information about trafficking in Argentina and to call community to action.
