QuickTime Then and Now
QuickTime is 30 years old
How QuickTime looked like and how it is now:
QuickTime is an extensible multimedia framework developed by Apple Inc., capable of handling various formats of digital video, picture, sound, panoramic images, and interactivity. First made in 1991, the latest Mac version, QuickTime X, is currently available on Mac OS X Snow Leopard and newer. Apple ceased support for the Windows version of QuickTime in 2016, and ceased support for QuickTime 7 on macOS in 2018.
As of Mac OS X Lion, the underlying media framework for QuickTime, QTKit, was deprecated in favor of a newer graphics framework, AVFoundation, and completely discontinued as of macOS Catalina.
