Viral videos can reach global penetration traveling through international channels of communication similarly to real diseases start- ing from a well-localized source. In past centuries, disease fronts propa- gated in a concentric spatial fashion from the the source of the outbreak via the short range human contact network. The emergence of long- distance air-travel changed these ancient patterns. However, recently, Brockmann and Helbing have shown that concentric propagation waves can be reinstated if pro
