The World's Greatest Magic was a series of American television specials showcasing magic acts. The first of five shows was broadcast by NBC in 1994, and continued with annual editions through 1998. These shows were most often first telecast during the Thanksgiving holidays when special programming would occur.
The first episode was hosted by Robert Urich, the second by Alan Thicke, and the final three episodes by John Ritter. Before each commercial break of every episode, in a segment known as the Mac King School of Magic, Mac King showed viewers a simple magic trick, and would break its steps down after the commercial break so that the audience could perform the same trick for family and friends.
