Thirty years ago I was in college and workign summers for my Dad's computer leasing company. On August 12, 1981 he walked in and showed me this full page Wall Street Journal ad that Apple had taken out on the day the IBM Personal Computer was announced. He said it was a very big deal, and that turns out to have been quite an understatement. IBM didn't create the PC business or even stay in it over time, but this was arguably the most important PC announcement ever. It's hard to imagine now what an unprecedented move it was by IBM to offer an open platform using hardware and software built by other companies. It was a bold and classy move by Apple to take out the ad, and the copy is pretty amazing to look back on. It's also interesting to note that this week was the first time Apple's market cap was the most valuable in the world.
Here's a video by CNET's Rafe Needleman that looks back 30 years ago at the IBM PC's Launch. It includes an interview with the guy who invented Control-Alt-Delete, and a video of him on a panel where he says to Bill Gates "I may have invented Control-Alt-Delete but Bill made it famous." Bill then gives him a death stare that would have made Andrew Mason from Groupon proud.
