I would say the height of StumbleUpon would be the late 00s through the early 10s, so not the early Internet. I think a better term would be “the early-middle Internet”, if anything, if we’re to assume today is the middle Internet (which I personally think is fairly reasonable).
(Assuming by “Internet”, we’re only referring to the Internet as it has existed in the Age of the WWW.)
