Corporate Universities (CUs) are a growing trend in companies. Corporate Universities are anything from a pumped up training department to a degree granting branch of major companies. (etc.)

Not sure what the question is, but here is some explanation:

This paper discusses the emerging model of "corporate university" (CU) for continuous learning in the corporate world. With specially tailored training, CUs aim at improving the productivity and skills of employees using the latest advances in information and telecommunication technology. Training in this model particularly is more responsive to corporate needs than other learning intervention methods and adds value to the company business goals by helping recruit and retain talent. Their special focus is on disseminating common culture and driving changes in the entire organization.

Corporate Universities (company universities) are run by companies for their internal training purposes and sometimes also for the needs of general public. As you can see from the definition provided by Nesrin, they may range from "training departments" to "full size" institutions offering degrees such as MBA etc.
