Totally agree and earlier I stated that may be the label of decipline would be different(or even emerged in other deciplines). Still I believe some parts are unique, such as knowledge management. the point is that IS is a context for other managerial studies, a context which is unique. sticking to topic, I wanted to point this out that even if someone graduate from an IS department and hypothetically 5 years later there is no IS department in US , still academic jobs are availabe although IS graduates may work in a marketting or accounting program
