The use of the word person in the fields of sociology, politics, marketing and –above all- Communications has become increasingly more frequent. For instance, it is held that commercial communication –a privileged field where several of above-mentioned converge– does not want to deal with customers any more, but with people. Is this simply a fashionable catchphrase like any other advertising trend? This work is based on the hypothesis that, even when recognizing the superficiality of many of its uses, its frequent use has to do with the philosophical current of Personalism. The same semantics and etymology of the word person justifies its relevance in the communications field. In order to demonstrate this, the main authors and theories related to this term are briefly summarised, while at the same time highlighting potential applications and common ground for Communications with a special accent on new technologies.
