Comment Quern. Or (flint) knapping. Or gas lights. (Score 1) 790
More points for the longer they lasted (typewriters were around for over a century).
A quern is a hand-powered grindstone. Practically every house in the world - well, the world grinding grain to make bread or porrage/ pottage/ gruel - used one from the dawn of seed gathering (centuries to millennia before the dawn of agriculture) until about the start of the industrial revolution. Say, between 10 and 20 thousand years.
They only went out of use when it really became cheaper and easier to take your grain to the mill to get it ground by wind/ water/ horse power instead of indulging in (literally) "the daily grind".
If you want a million or two years more of duration, then you could go for the sound of stone on stone, making a new stone tool. More latterly, depending on region, antler on stone, but that's probably only a few tens of thousands of years.
Oh, you wnat something technological?
How about the "pop" of a gas light lighting within it's mantle? These days you probably won't even hear it on a camp site - just the click of an LED switching on/off - but for a century or so it represented the chemical industry, the first large-scale "to the door" distribution network (home many optical fibres still run in trenches originally cut for gas pipes?) ; the billing that went with it, needing computers (human ones, then adding machines, then typewriters).
