Adobe Illustrator is a vector-based drawing program developed and marketed by Adobe Systems.

History

Adobe Illustrator was first developed for the Apple Macintosh in 1986 (shipping in Jan 1987) as a logical commercialization of Adobe's in-house font development software and PostScript file format.

Initial release

In many ways Illustrator's release was a gamble: the Macintosh did not have high market share, the only printer that could output Illustrator documents was Apple's own LaserWriter (also very new and expensive), and the drawing paradigm of Bézier curves was novel to the mainstream user. Not only did the Macintosh show only monochrome graphics, but display options were basically limited to its built-in 9" monitor. Illustrator helped drive the development of larger monitors for the Macintosh.

Illustrator was a reliable, capable product, however, and its relatively low learning curve let users quickly appreciate that the new paradigm was not only better, but finally solved the problem of imprecision from existing programs like MacDraw. It also provided a tool for people who could neither afford nor learn high-end (and perhaps overkill) software such as AutoCAD. Illustrator successfully filled a niche between painting and CAD programs.

Illustrator's power and simplicity derive from the choice of Bézier curves as the primary document element. A degenerate curve provides a line, and circles and arcs (trigonometric shapes) can be emulated closely enough. In a novel twist, Adobe also made Illustrator documents true PostScript files -- if one wanted to print them, one could send them directly to a PostScript printer instead of printing them from Illustrator. Since PostScript is a readable text format, third-party developers also found it easy to write programs that generated Illustrator documents.

Versions 1.1–3

Illustrator 1.0 was quickly replaced by 1.1, which enjoyed widespread use. An interesting feature of Illustrator 1.1's packaging was the inclusion of a videotape in which Adobe founder John Warnock demonstrated the program's features. The next version (in a novel versioning scheme) was 88 (to match the year of release which was 1988). That was followed by 3.0, which emphasized improved text layout capabilities, including text on a curve. At around this time, Aldus had their FreeHand program available for the Macintosh, and despite having a higher learning curve and a less-polished interface, it could do true blend (gradient) fills, which kept FreeHand as a "must have" in DTP shops along with the rest of the "Big Four": Illustrator, PageMaker, and QuarkXPress. It would be many years before Illustrator supported true blended fills (in Illustrator 5), and this was perhaps the one feature that users uniformly complained was lacking.

Adobe was willing to take risks with Illustrator's user interface. Instead of following Apple's UI guidelines to the letter or imitating other popular Macintosh programs, they made it possible to switch between the various navigation tools (i.e, Zoom and Pan) using various keyboard key combinations. Probably from Adobe's past experience in-house, it knew what it was doing, and the majority of users vindicated the design as "slick." Unfortunately, Apple later chose one of the key combinations (Command-Space) as the keyboard layout changer, and Windows treated another (the Alt key) as a system key.

Versions 2-5

Although Adobe developed Illustrator primarily for the Macintosh during its first decade, it sporadically supported other platforms. In the early 1990s, Adobe released versions of Illustrator for NeXT, Silicon Graphics IRIX, and Sun Solaris platforms, but they were discontinued due to poor market acceptance. The first version of Illustrator for Microsoft Windows, version 2.0, was released in early 1989, but it was a flop. The next Windows version, version 4.0, was widely criticized as being too similar to Illustrator 1.1 instead of the Macintosh 3.0 version, and certainly not the equal of Windows' most popular illustration package CorelDraw. (Note that there were no versions 2.0 or 4.0 for the Macintosh.) Version 4 was, however the first version of Illustrator to support editing in preview mode, which did not appear in a Macintosh version until 5.0 in 1993.

Versions 6–7

With the introduction of Illustrator 6 in 1996, Adobe made critical changes in the user interface with regards to path editing (and also to converge on the same user interface as Adobe Photoshop), and many users opted not to upgrade. To this day, many users find the changes questionable. Illustrator also began to support TrueType, making the "font wars" between PostScript Type 1 and TrueType largely moot. Like Photoshop, Illustrator also began supporting plug-ins, greatly and quickly extending its abilities.
