Yahoo has launched a web-based version of its free instant messaging service, allowing users to access their instant messaging contacts when on a computer with an Internet connection but without the Yahoo! Messenger software. Their slogan is "IM from any browser. Anywhere." implying that the service supports Internet Explorer, Firefox as well as the less popular Opera and Safari. Industry statistics indicate that nearly a quarter of US Internet users go online from places other than home or work. The web-based version still allows users of Yahoo's instant messaging system to converse with people using Microsoft's Windows Live Messenger. The service is initially launching in Brazil, India, Malaysia, Philippines, Vietnam and the United States. It is to be made available in other countries through the rest of the year.
