Bob's debut

Microsoft, the world's largest software manufacturer, introduced Bob at the weekend - a user-friendly software designed to increase the usefulness of computers at home.

Microsoft's chairman, Bill Gates, told guests at a consumer electronics show that the software, to go on sale in March, would make computer use more accessible. The package marks the first time Microsoft has developed software that specifically targets home computer users.

Bob features a cartoon character programmed to help beginners wade through the eight basic programs. Microsoft has dubbed the feature "social interface" as it is designed to help users with little or no computer skills.
