This article, our sixth annual survey of electronic contracting cases, discusses the significant electronic contracting cases decided between June 15, 2009 and June 15, 2010. Over the past six years, the law of electronic contracts has matured, and the cases we discuss in this article show this maturation. The survey covers contract formation by the use of shrinkwrap, clickwrap and browsewrap terms, and contract formation by the exchange of e-mail messages.
