This article reviews recent research on social media platforms as outlets of street protest reporting by activists, posing the question of whether such outlets constitute a cultural source for protest movements. Given the "many-tomany" dynamic that alternative journalism via social media offers in contrast to the "one-to-many" approach of traditional media, there are implications for incursions into more democratic, participatory cultures and structures. Existing literature indicates that user-generated content via social media potentially is known to supplant traditional journalism in protest situations due to advantages such as firsthand access. Further, research demonstrates that activist reporting supplements and integrates with traditional journalism, and that interdependence develops. We also review the boundary conditions that constrain the use of socialmedia platforms for protest reporting. 1 | INTRODUCTION In January 2011, tens of thousands of Egyptian activists mesmerized the globe as they occupied Cairo's Tahrir Square, ultimately resulting in the resignation of Egypt's President Mubarak. This spectacle, and the accompanying domino pattern of "Arab Spring" (or "Arab Awakening") uprisings across the Middle East and North Africa exemplified the near ubiquity of global access to digital devices, the internet, and social media, allowing previously unparalleled speed and reach (Bossio, 2014, p. 22; Radi, 2017). In concert with other 21st-century movements such as #OccupyWallSt, #Blacklivesmatter, #MeToo, #hongkongprotests, #OccupyGezi, and #indignado, these activists purposed technology-assisted platforms to message organizing details, live-stream events, document police actions, disseminate protest music and art, host on-line debates, and more (Castells,
