At no point, but those were the examples you gave to justify videogames as a sport. My argument is that all the spectacle, endorsements, celebrity, and humongous salaries are none of the things that constitute a sport.
Objectively, a sport is an athletic endeavor showcasing the athlete's physical ability and endurance. Strength, speed, agility; these are the qualities on display in sports. Botton pushing is not a sport. The ability guzzle Monster to stay awake is not a display of physical prowess or endurance.
