The PESO model, developed in 2014 by Gini Dietrich, an American public relations expert and founder of Spinsuck, is an evolved version of the 2004 model. It serves as a guide for measuring and representing the results of public relations activities. This model divides the field of intervention into four key areas: paid media, earned media, shared media, and owned media. Unlike the previous model popularized by Forrester, the PESO model is specifically designed for public relations, thus excluding elements such as television advertising, which do not fall directly within this field.

One of the distinctive features of the PESO model is its clear distinction between earned and shared media, a distinction absent in its predecessor, the POEM model. Furthermore, it highlights areas of overlap between these different areas, allowing, for example, the insertion of a communication strategy into the common area between shared and owned media. While some criticisms can be leveled at the innovative nature of PESO compared to POEM, it offers the advantage of clarifying previously conflated concepts. Furthermore, the PESO model can be adapted to a broader marketing context than just public relations, thus requiring adjustments to the components and characteristics of different sectors.
