Lee Aase discusses Mayo Clinic's use of social media for marketing. He notes that word of mouth has long been very effective for Mayo Clinic, with 91% of patients recommending it and 85% recommending it to a friend. However, an elderly couple's piano playing video uploaded to YouTube gained over 4.7 million views after Mayo Clinic shared it on social media platforms, demonstrating their powerful promotional potential. Aase advocates that organizations provide a free way to experiment with social media before fully committing resources to it.
