This fall, 19.9 million college students will be traveling to college campuses across the United States to start a new school year. There are over 4,000 colleges and universities in the United States, but Harvard Business School professor Clayton Christensen says that half are bound for bankruptcy in the next few decades.
Christensen is known for coining the theory of disruptive innovation in his 1997 book, "The Innovator's Dilemma." Since then, he has applied his theory of disruption to a wide range of industries, including education.
In his recent book, "The Innovative University," Christensen and co-author Henry Eyring analyze the future of traditional universities, and conclude that online education will become a more cost-effective way for students to receive an education, effectively undermining the business models of traditional institutions and running them out of business.
