Yahoo!
Yahoo grew rapidly throughout the 1990s. Yahoo went public in April 1996 and its stock price rose by 600 percent within two years. Like many search engines and web directories, Yahoo added a web portal, putting it in competition with services like Excite, Lycos and America Online. By 1998, Yahoo was the most popular starting point for web users, and the human-edited Yahoo Directory the most popular search engine, receiving 95 million page views per day which was triple the number compared to rival Excite. It also made many high-profile acquisitions. Yahoo began offering free e-mail from October 1997 after the acquisition of RocketMail, which was then renamed to Yahoo! Mail. In 1998, Yahoo! decided to replace AltaVista as the crawler-based search engine underlying the Directory with Inktomi. Yahoo's two biggest acquisitions were made in 1999 - that of Geocities for $3.6 billion, and Broadcast.com for $5.7 billion.
Juno Online Services
Juno was founded in May 1996 by Charles Ardai, Brian Marsh and Clifford Tse, with equity capital provided by the D.E. Shaw Group and headquarters in the same Midtown Manhattan building as Shaw. In August 1996, it began a free e-mail service –- a customer would install the proprietary Juno client which would allow them to send and receive email of about 35 kilobytes in size. Version 1 did not offer attachments or other features. The user could write emails with the Juno client and would periodically sign in by dial-up. Upon doing so, the Juno client would upload any emails the user had written, download any new incoming emails in the online mailbox, and download targeted advertisements, which were displayed in the client. This was similar to "QWK" and similar less automated offline readers that had been used for years by BBSes to save phone line connect time.
