Interactivity in television (and sustainability, thanks to virtualization) is a growing phenomenon, driven especially by the implementation of the HbbTV (hybrid broadcast broadband television) standard. Networks, media agencies and advertisers are trying to adapt to and profit from the options generated by the interaction with the viewer. Through an experimental methodology including the viewing of an advertising block which included conventional and interactive advertisements, the emotions of the viewer were collected. It was concluded that the order of the announcements is not decisive, that the emotions of anger and sadness predominate over those of joy due to a negative predisposition towards viewing advertising proposals and the content of the advertisement itself, and that less intrusive formats are more accepted.
