RocketMail was one of the first major free webmail services. The service was originally a product of Four11 Corporation. For a brief time, RocketMail battled with Hotmail for the number-one spot among free webmail services. Four11, including RocketMail, was acquired by Yahoo! in 1997 for $92 million. Yahoo! assimilated the RocketMail engine. Yahoo! Mail was essentially the old RocketMail Webmail system.
