My dad remembers watching the moon landing in Bangladesh, and someone commenting on how it couldn't be possible because "you can't punch a hole in the sky." I don't think he could tell you when he switched from Altavista to Google.
A friend's grandmother told the story of doing laundry in Malta as a young girl, and dreaming with her friends, wishing that there was some sort of 'magic box' you could throw the clothes in, press a button, and have them come out clean.
When the washing machine came out where she was - even though it's an utterly boring item to all of us - it massively changed how she lived her life.
