It has the format of the Argentine documentary film Algo habrán hecho por la historia argentina, and it was aired by Televisión Nacional de Chile as part of the Bicentennial of Chile celebrations.

The documentary is hosted by historian Manuel Vicuña and the actor Francisco Melo, reprising the roles of Felipe Pigna and Mario Pergolini in the Argentine documentary.

The documentary was based on investigations by Andrea Larroucau, Juan Carlos Arellano, Jorge Martin, Carolina Odone and María José Schneuer, and the support of Hernán Rodríguez, Alejandra Araya and Fernando Purcell.

The second style is the plain explanation of the things taking place, which could be done with visual gags, with the hosts in some modern day location, or at a representation of an event.

The use of jokes or visual gags, however, is very limited, and the documentary does not have the humoristic tone of the Argentine one; and the acted passages are longer and more detailed.
