free sheets of paper to students

I met a website and the idea is very interesting for me.
A company called Free Hand Advertising a new concept to reach university students in an innovative way.
They distribute 4 sheets of paper to each students every day. On the top of paper there is an advertisement of a company.
So, the companies can reach the university students as they take notes , which is not less than 90 minutes a day.
So, both sides students and advertisers are happy.......
Nice idea.
