27 years ago today, Steve Jobs showed off the first Macintosh computer to the world. This Stevenote was given in front of a live audience on January 24, 1984, two days after the famous Apple Super Bowl commercial from 1984. Below is a video of the presentation by Steve Jobs. The Mac has changed a lot over the years but judging by the crowd reaction, the fanaticism of Mac fanboys hasn’t. Happy Birthday Macintosh!
