While Google clearly dominates in search, Microsoft and Yahoo have both had higher numbers in email for as long as Gmail has existed.

Gmail is much younger, however. And while Gmail still has a way to go before overtaking these other services especially Yahoo, it is no secret that Google has been gaining. Earlier this year, WebProNews spoke with Yahoo Mails VP John Kremer about Yahoos expectations for its own email service, and the threat of Google. He saidWeve been the most popular Webmail service in the US and a worldwide leader for years, and we will continue to lead from the front of the pack not by looking in the rearview mirror, says Kremer.
