For some reason, I have been asked to follow up on the great articles by Patrick Prosser and Gilles Pesant on articles with impact. Maybe this has to do with the fact that I started working in that field quite a long time ago, in 1989. As Patrick said, it was before lots of things taken for granted now (world wide web, mobile phones for everyone, Java, laptops, Google, etc) existed. Note that we were no longer using punch card either, we even had Apple Macintoshes in my lab, and we were connected to Internet! Still, can you imagine an Internet without the web?
