Corporate universities (CUs) are a growing tren in corporations. Corporate universities are anything from a pumped up training department to a degree granting branch of major companies. Denise Hearn, in her article "Education in the Workplace: An Examination of Corporate University Models," notes that in 1993 corporate universities existed in only 400 companies. By 2001, this had number increased to 2,000, including Walt Disney, Boeing, and Motorola. Many experts in the field expect the popularity of corporate universities to continue to grow.[who?]
