There are three main components to the QuickTime technology. There is the QuickTime file format itself which is openly documented and available for anyone to use royalty-free. Apple develop a QuickTime media player which they make available for free download on their website, as well as bundle with every one of their computers. Lastly there are software development kits available for the Macintosh and Windows platforms, that allow people to develop their own software to manipulate QuickTime and other media files.

The commercial aired on January 22, 1984 during the 3rd quarter of Super Bowl XVIII. on a Mac, at the time an astounding technological breakthrough. Microsoft's competing technology Video for WindowsVideo for Windows was a multimedia technology developed by Microsoft that allowed Microsoft Windows to play digital video. Overview Video for Windows was first introduced in November 1992 as a reaction to Apple Computer's QuickTime technology which added did not appear until NovemberNovember is also the letter N in the NATO phonetic alphabet.

That first version of QuickTime laid down the basic architecture which survives essentially unchanged today, including multiple movie tracks, extensible media type support, an open-ended file format, and a full complement of editing functions. Among the original video codecs were the Apple Video codec (also known as "Road Pizza"), which was suited to normal live-action video; the Animation codec, which used simple run-length compression and was better suited to cartoon-type images with large areas of flat colour; and the Graphics codec which was optimized for 8-bit-per-pixel images, including ones which had undergone dithering.
QuickTime 1.5 for Mac OS was released in the latter part of 1992. This added the SuperMac-developed Cinepak vector-quantization video codec (initially known as Compact Video), which managed the unheard-of feat of playing back video at 320*240 resolution at 30 frames per second on a 25MHz 68040 CPU. It also added text tracks, which allowed for things like captioning, lyrics etc at very little addition to the size of the movie.
In an effort to increase the adoption of QuickTime, Apple contracted an outside company San Francisco Canyon Company to port QuickTime to the Windows platform. Version 1.0 of QuickTime for Windows, was only a subset of the full QuickTime API, including only movie-playback functions that were driven through the standard movie controller.
QuickTime 1.6.x came out the following year. 1.6.2 was the first version to incorporate the "QuickTime PowerPlug" which replaced some components with PowerPC-native code when running on PowerPC Macs.
QuickTime 2.0 for Mac OS was released on February 1994. This was the only version that was never released for free. It added support for music tracks, which contained the equivalent of MIDI data and could be used to drive a sound-synthesis engine built into QuickTime itself (using sounds licensed from Roland), or any external MIDI-compatible hardware, thereby producing sounds using only small amounts of movie data.
The next versions, 2.1 and 2.5, reverted to the previous model of giving QuickTime away for free. They improved the music support and added sprite tracks which allowed the creation of complex animations with the addition of little more than the static sprite images to the size of the movie.
QuickTime 2.0 for Windows was released in November 1994.
QuickTime 3.0 for Mac OS was released on March 30 1998. This introduced the now-standard revenue model of releasing the software for free, but with additional features of the Apple-provided QuickTime Player and Picture Viewer applications that could only be unlocked by buying a QuickTime Pro licence code.
QuickTime 3.0 added support for graphics importer components that could read images from GIF, JPEG, TIFF and other file formats, and video output components which were primarily a way to export movie data via FireWire. It also added video effects which could be applied in real-time to video tracks. Some of these effects would even respond to mouse clicks by the user, as part of the new movie interaction support.
QuickTime 4.0 for Mac OS was released on June 8 1999. This added graphics exporter components which could write some of the same formats as the previously-introduced importers could read, though interestingly not GIF. It added the first version of the Sorenson video codec, and support for streaming.
QuickTime 4.1, released at the beginning of 2000, added support for movie files larger than 2 gigabytes on Mac OS 9.0 and later and dropped support for 68K Macs. The QuickTime Player could now be controlled via AppleScript.
QuickTime 5.0 for Mac OS was released on April 23 2001. It added "skins" to the QuickTime Player and multiprocessor image compression support.
QuickTime 6.0 for Mac OS was released on July 15 2002. This was the first to include a version for OS X.
