Some of the notable ones are, of course, Microsoft, IBM, and Apple. Yes, I know Apple builds hardware, but they also build software. In fact, I would argue that it's their software that makes their hardware so appealing.
But I'll throw out some names that were huge when Alpha Software first started 26 years ago who are now nothing more than footnotes in the history of computing. Ashton-Tate, WordPerfect, XyWrite, Quarterdeck, PFS, Digital Research, and WordStar.
There's another name that is also a footnote, but it's a footnote that spawned the industry. That company was Software Arts, Inc., which created VisiCalc. It was the first commercial spreadsheet for the Apple II. VisiCalc legitimized the personal computer, and spawned the industry that we know today. It was the first killer app that businesses could use right away and get real benefits from.
Here we are 29 years later, and Alpha Software is still around. And it's for one reason. We've ensured that our Alpha Five platform has kept pace with the changes and developments in the industry. If you're a long-time user of Alpha, you know how we've taken our developers from DOS, to Windows, to the Web, to the cloud, and now to mobile.
