Image description: In January 1984, Apple Inc. introduced a graphic user interface to its new computers. The idea had originated at Xerox’s Palo Alto Research Center in the 1970s, but Xerox was slow to commercialize it. Apple proved far more successful when it introduced the Macintosh with a splashy television advertisement during Super Bowl XVIII. The original price was around $2,500.
