Google Inc. is set to introduce its own instant messaging system, the Los Angeles Times reported on Tuesday, marking the expansion by the Web search leader into text and also voice communications, Reuters reported. Citing unnamed sources "familiar with the service," the Los Angeles Times said that Google's Instant Messaging program would be called Google Talk and could be launched as early as Wednesday. Google Talk goes beyond text-based instant messaging using a computer keyboard to let users hold voice conversations with other computer users, the newspaper quoted a source as saying. A Google spokeswoman declined to comment on the company's product plans. If confirmed, the combined computer text and voice-calling service would put Google in competition with a similar service pioneered by Skype, which has attracted tens of millions of users, especially in Europe, to its own service. Separately, independent journalist Om Malik on his blog at http://gigaom.com/ pointed to technical clues that suggest Google is preparing to run an instant messaging service based on an open-source system known as Jabber. Jabber technology would allow Google instant message users to connect with established IM systems that also work with Jabber, including America Online's ICQ and Apple Computer Inc.'s iChat, Malik said. "This is the worst possible news for someone like Skype, because now they will be up against not two but three giants who want to offer a pale-version of Skype," he wrote. Earlier this week, Google said it was branching out beyond pure search to help users manage e-mail, instant messages, news headlines and music. It introduced a new service called the Google Sidebar, a stand-alone software program that sits on a user's desktop and provides "live" information updates. --mor 1516 Local Time 1216 GMT
