Microsoft
In 1990, Microsoft introduced its office suite, Microsoft Office. The suite bundled separate productivity applications, such as Microsoft Word and Microsoft Excel. On May 22, Microsoft launched Windows 3.0, featuring streamlined user interface graphics and improved protected mode capability for the Intel 386 processor. Both Office and Windows became dominant in their respective areas.
Office Assistant
First introduced in Microsoft Office 97, the Office Assistant was codenamed TFC during development. It appeared when the program determined the user could be assisted with using Office wizards, searching help, or advising users on using Office features more effectively. It also presented tips and keyboard shortcuts. For example, typing an address followed by "Dear" would cause the Assistant to appear with the message, ""It looks like you're writing a letter. Would you like help?"".
