Sk8 or SK8 may refer to:
Sk8 is a half-hour teen drama that aired on NBC's TNBC Saturday morning programming block from October 6, 2001 to January 5, 2002 with 13 episodes produced. The show continued in reruns until TNBC's dissolution in September 2002.
The series was co-created by Thomas W. Lynch, who also co-created Just Deal, TNBC's first single-camera format series, with Sk8 becoming the second series on the lineup to be shot in the same format.
The show featured storylines concerning the life of an aspiring pro skater and his relationships with a motley crew of friends. The show featured guest appearances by professional skateboarders and guerrilla film and video shooting styles.
SK8 (pronounced "skate") was a multimedia authoring environment developed in Apple's Advanced Technology Group from 1988 until 1997. The project's goal was to allow creative designers to create a complex, working application. The main components of SK8 included the object system, the programming language, the graphics and components libraries, and the Project Builder, an integrated development environment. It was described as "HyperCard on steroids".
For much of its history, SK8 remained a research project, and inspired a number of other Apple projects like AppleScript, as well as seeing use as a prototyping platform. Although around 1993 a team was assigned by the Apple Product Division to release a SK8 runtime, the limitation of the Mac's capabilities as well as the shift to the PowerPC chip made such a large project intractable. With the bulk of the original vision completed and no easy path to release as part of MacOS, active development ended in 1996-1997, and the Macintosh Common Lisp source code for the entire project was released to the public in 1997.
