When most of his peers were still struggling to make pocket money through part-time weekend jobs, 16-year-old British young entrepreneur Jonathan Grubin had already made his first pot of gold through the three websites he had set up. He earned 75,000 pounds (about 150,000 US dollars) only last year. Grubin made money without going out of his home, and instead, he took advantage of the "affiliate marketing" model, that is, opening a website, enrolling members, recommending products to the members, and finally obtaining commission from advertisers.
