Notehall is an online marketplace, in which college students can buy and sell class notes. Notehall gained recognition after appearing on the ABC reality show Shark Tank in October 2009. It has since been purchased by Chegg, a textbook-rental company, for $3.7M in equity and undisclosed cash. Notehall.com was later integrated into the Chegg Homework Help site.
