This work investigates the contributions of Robert Craig to the theory of communication. The American academic is practically unknown in the Latin American academy with few exceptions. On the one hand, the contributions of Latin American communicators in the main international communication magazines are still scarce, which increases their invisibility, and on the other, these magazines seem not to be too interested in Latin American production. For long years, communication theories sought to find a shared definition for their object of study and a model that faithfully expressed the communicative process.
