Marcus Rivers (portrayed by child-actor Bobb'e J. Thompson) is a fictional 12-year-old character that was used by Sony Computer Entertainment America as part of their Step Your Game Up advertising campaign for the PlayStation Portable and PSPgo consoles in North America, much like the PlayStation 3's "It Only Does Everything" advertising campaign commercials with Kevin Butler. He started as the publicist of the PlayStation Portable division of Sony, responding to "Dear PSP" queries. The character was created by Deutsch/LA, the advertising agency responsible for the campaign. The YouTube channel "marcuspsp" that hosted his videos, was closed in June 15, 2011 for an undisclosed reason.
