Macintosh Launched

The Original Macintosh ComputerJanuary 24, 1984

Apple Computer, Inc. launches the Macintosh computer with a demonstration of the computer in front of 3,000 people. While the Apple Lisa was the first commercial computer with a graphical interface, the Macintosh would bring graphical computing, and computing in general, to “the rest of us”, as Apple’s early slogan for the Macintosh claimed. While not as commercially successful as Microsoft’s DOS and later Windows, there is no doubt that the innovations of the Macintosh pushed the entire computing industry ahead and continue to do so to this day.

1984 Commercial Introduces the Macintosh

January 22, 1984

Apple Computer broadcasts their now-famous “1984” commercial introducing the Macintosh, during the third quarter of Super Bowl XVIII. It was the first and last time the ad was truly broadcast. However, it is a little-known piece of trivia that the ad was aired one other time at 1 AM on December 15, 1983 in Twin Falls, Idaho, but only so that the advertisement could be submitted to award ceremonies for that year. A 30-second version also ran in theaters starting January 17, but it was the broadcast during the Super Bowl that people really took notice of.

I was 9 years old then and I vaguely remember seeing the commercial, but I also remember being more interested in watching the Raiders beat the Redskins at that time. It wasn’t until many years later that I actually recalled the commercial. Yet when I recalled it, it was as if I remembered that commercial all along. I guess even though I didn’t appreciate it at the time, I somehow knew that moment truly was changing the world.
