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.
History of Gmail
In January 2005, security experts discovered a critical flaw in the handling of Gmail messages that would allow hackers to easily access private emails from any Gmail user's account. This was posted with detailed information to popular technology site Slashdot at 9:23 a.m. PST on 12 January 2005. On 13 January 2005, developers at Gmail announced that they had fixed the problem and that the security flaw had been patched. Despite Gmail's status as a beta application, concerns were raised among some users who were using Gmail as their primary mail account. On 1 April 2005, exactly one year after the initial release, Gmail increased the mailbox size to 2 GB, advertising it as 2GB plus and introduced some other new features, including formatted editing which gave users the option of sending messages in HTML or plain text.
