**Abstract**

In the last 5 years, there has been great debate about digital communication and its role in electoral politics. The question on everyone's mind is: can viral and massive information on social networks change the voting tendencies and behavior of people? We expose a series of theoretical points from the perspective of semiotics and systemics, to understand these communication phenomena, which are hallmarks of the twenty-first century. We also include some cases of semiotic and systemic orientation and our proposal about natural and artificial communication through viral cascades.
