April 20, 1998. 22 years ago today. During the COMDEX Spring ’98 and Windows World shows in Chicago, a public demonstration of the soon-to-be released Windows 98 goes awry when Bill Gates’ assistant causes the operating system to crash after plugging in a scanner. Instead of showing the plug-and-play capabilities they were trying to demonstrate, a “Blue Screen of Death” is visible by the entire audience which immediately erupts in laughter. After several seconds, Bill Gates famously responded, “That must be why we’re not shipping Windows 98 yet.”

Ironically, the assistant, Chris Capossela, has moved up the executive ranks at Microsoft, recently being promoted to the position of Senior Vice President, Consumer Channels and Central Marketing Group. For Microsoft’s sake, hopefully he’ll present a much better marketing image then he did that fateful day!
