Yahoo blended its free e-mail and instant messaging services on Monday, making it simple for users to "chat" online from any computer connected to the Internet.Yahoo is the largest provider of web-mail service, according to ComScore industry tracker.
Yahoo said it will roll the service out in phases to its approximately 250 million e-mail users during the coming three months.This deep integration across Yahoo!'s e-mail and instant messaging services enables e-mail users to easily connect to contacts in Yahoo! Messenger's thriving IM community, without leaving the Web mail experience.People can choose to let others know if they are online and available to exchange messages in real time, and users will be able to see the online status of everyone in their contact list as well. Each instant messaging dialogue will take place in a new conversation tab within Yahoo! Mail beta, allowing people to chat with multiple friends simultaneously, without leaving the e-mail experience. Users can also convert e-mails seamlessly into IMs when friends come online .
