Giving away effective methods for mastering the world’s knowledge presents a Napster-like challenge for companies such as London-based Pearson and McGraw-Hill, which publish two of the most popular grade-school math textbooks and offer extensive online and digital components. For Pearson, the education segment in North America, comprising textbooks, online products, and test administration, represented $4.2 billion worth of business in 2010; for McGraw-Hill in 2009, it was $2.4 billion. Education Market Research estimates that the K-12 textbook market alone will reach $3.5 billion in the 2010-2011 school year.
The Khan Academy gives it away to 2M users (students). There are amazing things happening in the education business.
