The Davy Crockett miniseries on Disney's ABC show in 1954 went viral before the internet existed: 10 million coonskin caps, 7 million Ballad of Davy Crockett records at #1 on the charts, and ~$300 million in total gross merchandise sales. That $300M exceeded the cumulative profit from every Disney animated feature film ever released. And it all happened right before Disneyland opened.
