Business Insider recently interviewed Chegg CEO Dan Rosensweig who says the four year old company has services available on about 8,000 campuses and processes millions of orders a year. Yes, the article reported 8,000 campuses. Chegg’s additional services than other their core book rental business include Student of Fortune, a Q&A homework help site, and Notehall, a class notes marketplace. According to Rosenweig, Chegg wants to provide as much digital content to students as possible including class notes, books, and study groups.
Incidentally, Notehall ran into some legal troubles over its note taking business with some California State University students which violated campus copyright policy. Chegg has acknowledged the policy and has agreed shut down their note taking business at specific universities effective January 1, 2012.
Finally, Kno, which spun out of Chegg, is working on e-textbooks and a related delivery platform. Previously the company was working on a tablet type device, but subsequently withdrew that initiative. However, this month they unveiled their "free textbook campaign" where they tend to give away one free e-textbook to every user. A copy of their campaign ad appears below.
