LOUISVILLE, KY: Humana launched a viral healthcare education campaign called "Stay Smart Stay Healthy" on November 10. The Louisville, KY-based health insurer created 10 videos that are being uploaded to a new Web site and to a YouTube channel. The focus of the videos is "the big questions that consumers are asking us," said Edward Batchelor, corporate director of Web and new media strategy for Humana. Video topics include the definition of consumer-driven healthcare, the difference between HMOs and PPOs, and the history of healthcare in the US. There is no marketing or PR campaign in place but Humana is testing the "viral nature" of educational videos for future projects, Batchelor said.
