WordPerfect ruled the word processing market for almost 10 years, stumbling and then dying on the Windows market.
Almost Perfect, published in 1994, describes the rise and fall of the corporation, and it’s available online as a compelling read. An excerpt:
…Microsoft offered to make us a beta test site for Windows 3.0. We accepted their generous offer, but did little more than look Windows over. In hindsight, it is easy to see we should have done much more right away. At the time, we could justify not doing a Windows 2.0 version in favor of completing WordPerfect 5.1 for DOS, but it is now difficult to defend our further delays. Unfortunately, we did not have any experienced Windows programmers inside the company to form a development team, and there were not many outside the company to recruit.
