QuickTime was developed by Apple. The main intention of this is to give the end user a chance to play various formats of digital videos, pictures, sounds, animations, graphics and texts and music with an inbuilt media player. This software is bundled with OSx and is downloaded as a standalone installation. See Also: CallNote for MAC OS X.
