On June 15th, 1993 Adobe Acrobat 1.0 was introduced in New York.
Beforehand the software code named Carousel was tested over year. I was one of the early beta testers.
Acrobat 1.0 consisted of three different products which were sold separately. The editing software Acrobat Exchange (including PDF Writer), Acrobat Distiller for converting PostScript to PDF and Acrobat Reader for viewing PDF documents:
Acrobat Reader 1.0 was sold! At the beginning one could only buy Reader in packages of 50 for US$2500! This indicated that Adobe was mainly targeting large enterprises with Acrobat. Of course this did not help much increasing prevalence of the software. Breakthrough came only when Reader became free in version 2.0.
In the course of the years Adobe has made many, often incomprehensible changes in Acrobat product marketing (e.g. product names, forms, 3D). Despite these confusions (and many changes of the user interface) Acrobat is a success story for Adobe.
In these 25 years more than 100 millions Acrobat licenses were sold and more than a billion Readers distributed!
