Adobe created PostScript, but since then, almost everything has been an acquisition.<p>- Photoshop from Thomas and John Knoll<p>- PageMaker from Aldus<p>- FrameMaker from Frame<p>- Flash, Flex, Dreamweaver, ColdFusion, et al. from Macromedia<p>O.K., Illustrator was developed in-house, but you can almost call that a PostScript editor. And PDF is a more portable version.<p>I don't know the development history of Premier. A copy of Avid?<p>Well, I'm sounding pretty negative about Adobe as a tech innovator (I actually preferred the Macromedia vibe), but I've still paid my bucks for Creative Suite, and I'm a fan of their (mainly well-designed) tools.
