Studying online is much more effective than attending campus. Students do not have to leave their homes to listen to lecture or participate in tutorials. They can even interact with fellow peers just by using their laptops. For example, while online courses used to target working professionals who couldn't attend class, they now target anyone because universities have realised that people are time poor. In short, because of the enormous time savings that online courses allow, people prefer it rather than attending face to face classes.
