This TrueType font format was created in 1989 by Apple. It is made with a high level of font display control to the pixel. It is easily scalable because of its vector format. So, the TrueType font is used in OS from Microsoft to Apple.
It was created in the 1990s with four types of fonts; Helvetica, Courier, Pi, and Times New Roman. This font format was designed for use in Mac products to compete with Type 1 fonts present in Adobe's PostScript. With this, users control how the text will be viewed on the computer screen and the printed page. Adobe had the plans of making it available to Adobe users, but Apple licensed TTFs to be used on Microsoft products breaking Adobe's hold on proprietary fonts.
