Page "PostScript" Paragraph 24

Adobe's licensing fees were widely considered to be prohibitively high, and it was this issue that led Apple to design their own system, TrueType, around 1991.

Immediately following the announcement of TrueType, Adobe published the specification for the Type 1 font format.

Retail tools such as Altsys Fontographer ( acquired by Macromedia in January 1995, owned by FontLab since May 2005 ) added the ability to create Type 1 fonts.

Since then, many free Type 1 fonts have been released ; for instance, the fonts used with the TeX typesetting system are available in this format.
