Answer: America The Story of Us is an epic 12-hour television event that tells the extraordinary story of how America was invented. With highly realistic CGI animation, dramatic recreations and thoughtful insights from some of America’s most respected artists, business leaders, academics and intellectuals, it is the first television event in nearly 40 years to present a comprehensive telling of America’s history. Elaborate, ambitious and cinematic, America The Story of Us will take you into the moments when Americans harnessed technology to advance human progress, from the rigors of linking the continent by transcontinental railroad–the internet of its day–to triumphing over vertical space through the construction of steel structured buildings to putting a man on the moon.
