"It was the burgeoning TV markets that most influenced the American public’s perception of Godzilla not as destructive force, but as heroic monster with an appeal to children. Google’s nGram viewer shows recorded instances of the word “Godzilla” appearing in English language books starting only in 1970, one year after the 1969 Americanized version of Son of Godzilla was released directly to TV. The ability to remove large sections of the movies without sacrificing any of the over-simplified story made Godzilla a perfect fit for the few existing channels looking to maximize ad space in sparsely populated programming blocks. In 1977, NBC gave Godzilla vs. Megalon an hour long network television premiere with over twenty minutes trimmed from the film."
