How CBS' Supergirl Trailer Became a Viral Sensation

Clip has garnered more than 10 million views in just a week

George Schweitzer has spent 20 years overseeing the trailers for the new shows CBS unveils at its upfront presentations each May. "It used to be we showed them in Carnegie Hall, and then we put them away for a while," recalled Schweitzer, president of CBS Marketing Group. But as the networks began releasing their upfront trailers online in recent years, he said, "Now, it's shown in Carnegie Hall, and five minutes later, it's going around the world."
