There is an interesting story behind this website. The guy who started this website needs money for study. So for that he started a website and sold every pixel of the site. Every pixel costs 1 dollar and each one should buy atleast 100 pixels. So advertisers thought this is the best place to get advertisements because so many companies are covered here. They want more space to show their company is great. so milliondollars got huge demand and the website owner got huge money.
