Adobe created PostScript, but since then, almost everything has been an acquisition. - Photoshop from Thomas and John Knoll - PageMaker from Aldus - FrameMaker from Frame - Flash, Flex, Dreamweaver, ColdFusion, et al. from Macromedia O.K., Illustrator was developed in-house, but you can almost call that a PostScript editor. And PDF is a more portable version. I don't know the development history of Premier. A copy of Avid? 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.
