Apple Macintosh is a line of computers introduced by Steve Jobs and Steve Wozniak of Apple Inc. on January 24th, 1984. The first computer in the line was called Mac 128K, and although it was a less expensive successor to the Apple Lisa, it was also less advanced. The Mac 128K was known for its easy-to-use GUI that utilized icons, windows, and a mouse for point and click operation as opposed to the IBM computers at the time, which used MS-DOS.
Macintosh (often abbreviated as Mac) computers first gained popularity amongst consumers with a famous commercial shown during the 1984 Super Bowl. The line continues today with the latest models under the name iMac for desktop computers and MacBook for laptop computers.
