By 1993, Windows had become the most widely used GUI operating system in the world. "Fortune Magazine" named Microsoft as the "1993 Most Innovative Company Operating in the U.S." The year also marked the end of a five-year copyright infringement legal case brought by Apple Computer, dubbed Apple Computer, Inc. v. Microsoft Corp., in which the ruling was in Microsoft's favor. Microsoft also released Windows for Workgroups 3.11, a new version of the consumer line of Windows, and Windows NT 3.1, a server-based operating system with a similar user interface to consumer versions of the operating system, but with an entirely different kernel. As part of its strategy to broaden its business, Microsoft released Microsoft Encarta on March 22, 1993, the first encyclopedia designed to run on a computer. Soon after, the Microsoft Home brand was introduced – encompassing Microsoft's new multimedia applications for Windows 3.x., Microsoft changed its slogan to ""Where do you want to go today?"" in 1994 as part of an attempt to appeal to nontechnical audiences in a US$100 million advertising campaign.
