Myriad is a humanist sans-serif typeface designed by Robert Slimbach and Carol Twombly for Adobe Systems. Myriad was intended as a neutral, general-purpose typeface that could fulfill a range of uses and have a form easily expandable by computer-aided design to a large range of weights and widths. Myriad is known for its usage by Apple Inc., replacing Apple Garamond as Apple's corporate font from April 29, 2002, to January 24, 2017. Myriad is easily distinguished from other sans-serif fonts due to its "y" descender (tail) and slanting "e" cut. Design Myriad is a humanist sans-serif, a relatively informal design taking influences from handwriting. Its letterforms are open rather than "folded-up" on the nineteenth-century grotesque sans-serif model, and its sloped form is a "true italic" based on handwriting. The 'g' is single-storey and the 'M' has sloped sides on the model of Roman square capitals. As a family intended for body text and influenced by traditional book printing, text figures are included as well as lining figures at cap height. Twombly described the design process as one of swapping ideas to create a "homogeneous" design but said that in retrospect she found the experience "too hard" to want to repeat. Myriad is similar to Adrian Frutiger's famous Frutiger typeface, although the italic is a true italic unlike Frutiger's oblique; Frutiger described it as "not badly done" but felt that the similarities had gone "a little too far". The later Segoe UI and Corbel are also similar. During the 1990s, Adobe developed a release of Myriad in the multiple master format, an ambitious format intended to allow the user to fine-tune weight, width and other characteristics of the design to their preferred form. The concept was not widely supported by third-party applications, and so most releases of Myriad have been in the form of separate font files. The concept has since been redeveloped as part of the OpenType variable fonts technology. Variations Myriad (Type 1) This PostScript Type 1 font family was released after the original Myriad MM. It initially included four fonts in two weights, with complementary italics. All these Type 1 versions supported the ISO-Adobe character set; all were discontinued in the early 2000s. Myriad Condensed It was a condensed version, released around 1998. The condensed fonts comprise three weights, with complementary italics. Myriad Headline A "Headline" version was also released, which has the weight of Myriad Bold, but
