Christensen was the best-selling author of ten books, including his seminal work "The Innovator's Dilemma" (1997), which received the Global Business Book Award for the best business book of the year. One of the main concepts depicted in this book is also his most disseminated and famous one: disruptive innovation. The concept has been growing in interest over time since 2004, according to Google Trends' data. However, due to constant misinterpretation, Christensen often wrote articles trying to explain the concept even further. Some of his other books are focused on specific industries and discuss social issues such as education and health care. "Disrupting Class" (2008) looks at the root causes of why schools struggle and offers solutions, while "The Innovator's Prescription" (2009) examines how to fix the American healthcare system. The latter two books have received numerous awards as the best books on education and health care in their respective years of publication. "The Innovator's Prescription" was also awarded the 2010 James A. Hamilton Award, by the College of Healthcare Executives.
