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 Online
Office Online (known before 2014 as Office Web Apps) is an online office suite offered by Microsoft, which allows users to create and edit files using lightweight Microsoft Office web apps: Word, Excel, PowerPoint and OneNote. The offering also includes Outlook.com, People, Calendar and OneDrive, all of which are accessible from a unified app switcher. Users can install the on-premises version of this service, called Office Web Apps Server, in private clouds in conjunction with SharePoint, Microsoft Exchange Server and Microsoft Lync Server.
