I've found that there is a certain mindset that only considers the last 18-24 months as "recent" in the tech space. It's probably a similar mindset to that which makes you feel that only the latest and greatest frameworks are worth learning, for example.

Right, but 24 months isn't enough time for a brand new startup to become a 'blockbuster'. None of the current big tech cos like Google, Amazon, Facebook, were a 'blockbuster' within 24 months of being founded. If you want to see that kind of startup success, you HAVE to look more than a couple years back. Startups can grow very quickly, but not THAT quickly.

True. I think a better metric is the last 18-24 months of breakouts, rather than foundings.
