A star of the NBC show Heroes admits the show declined in season 2 and says the last writers' strike was the culprit. “Save the cheerleader, save the world” became a ubiquitous tagline in 2006, as season 1 of the NBC superhero drama Heroes took over pop culture, becoming a ratings winner with an average of over 14 million viewers per episode.
