Editing HyperCard (section)

===HyperCard 2.0===
In late 1989, Kevin Calhoun, then a HyperCard engineer at Apple, led an effort to upgrade the program. This resulted in HyperCard 2.0, released in 1990. The new version included an on-the-fly [[compiler]] that greatly increased performance of computationally intensive code, a new [[debugger]] and many improvements to the underlying HyperTalk language.

At the same time HyperCard 2.0 was being developed, a separate group within Apple developed and in 1991 released HyperCard IIGS, a version of HyperCard for the [[Apple IIGS]] system. Aimed mainly at the education market, HyperCard IIGS has roughly the same feature set as the 1.x versions of Macintosh HyperCard, while adding support for the color graphics abilities of the IIGS. Although ''stacks'' (HyperCard program documents) are not binary-compatible, a translator program (another HyperCard stack) allows them to be moved from one platform to the other.

Then, Apple decided that most of its application software packages, including HyperCard, would be the property of a wholly owned subsidiary called [[Claris]]. Many of the HyperCard developers chose to stay at Apple rather than move to Claris, causing the development team to be split. Claris attempted to create a business model where HyperCard could also generate revenues. At first the freely-distributed versions of HyperCard shipped with authoring disabled. Early versions of Claris HyperCard contain an [[Easter Egg]]: typing "magic" into the message box converts the player into a full HyperCard authoring environment.<ref>{{cite magazine| magazine=[[MacTech]]| volume=10| issue=3|url=http://preserve.mactech.com/articles/mactech/Vol.10/10.03/Hypercard2.2/index.html| first=Paul| last=Foraker|title=Apple's taken HyperCard back from Claris. Here's what they've done with it|quote=Claris also tried an interim scheme of shipping a crippled, low user-level, Home stack, which users could override by typing 'magic' in the message box. There was some confusion between this version and the Player, that had people trying unsuccessfully to type 'magic' in the message box of the Player. The magic in HyperCard 2.2 is all plain and visible.}}</ref> When this trick became nearly universal, they wrote a new version, HyperCard Player, which Apple distributed with the Macintosh [[operating system]], while Claris sold the full version commercially. Many users were upset that they had to pay to use software that had traditionally been supplied free and which many considered a basic part of the Mac.

Even after HyperCard was generating revenue, Claris did little to market it. Development continued with minor upgrades, and the first failed attempt to create a third generation of HyperCard. During this period, HyperCard began losing market share. Without several important, basic features, HyperCard authors began moving to systems such as [[SuperCard]] and [[Macromedia Authorware]]. Nonetheless, HyperCard continued to be popular and used for a widening range of applications, from the game ''[[The Manhole]]'', an earlier effort by the creators of ''[[Myst]]'', to corporate information services.

Apple eventually folded Claris back into the parent company, returning HyperCard to Apple's core engineering group. In 1992, Apple released the eagerly anticipated upgrade of HyperCard 2.2 and included licensed versions of Color Tools and Addmotion II, adding support for color pictures and animations. However, these tools are limited and often cumbersome to use because HyperCard 2.0 lacks true, internal color support.
