Google’s April Fool’s Day pranks were well known, but in 2004, Larry Page and Sergey Brin surprised the world with the launch of Gmail. Offering 1GB of storage per account, Gmail revolutionized email storage at a time when other webmail services provided only a fraction of that capacity. The integration of Google’s search technology and threaded conversation feature made Gmail even more attractive. Today, Gmail has over 1.8 billion active users, each with 15GB of storage.
