There were a ton of shady internet companies capitalizing on this sort of hype and swindling people out of their hard earned money. Beanie babies were also huge.
Do you know what else was happening? The IETF was finding its feet as an org, RFCs were being written and iterated on, the building blocks of the modern internet were being built behind the scenes, and companies like Amazon were realizing that their value was not selling books but building a massive logistic network that could compete with brick and mortar stores. Porn companies (widely seen as morally reprehensible/unsightly) were also figuring out video streaming and PayPal was figuring out how to deal with online payments.
Yet, if you read the news and weren’t building in the space, you’d probably come to the same conclusions as you are today - the internet is a fad that will die out soon because there’s nothing of substance to it and it’s all just greater fool hype.
Zooming back to today - I’d implore you to go look at the research being done right now in the cryptography space - things like zero knowledge proofs, multi party computation, and threshold signature schemes are becoming more viable as building blocks every day. Same with a shift in mentality from centralized trust to decentralized control enabled by some of these cryptographic primitives.
Is every crypto project going to be the next Google? Of course not, but the entire point of putting VC money into the space is to push the space forward as a whole (along with spurring research), eventually leading to the next Amazon/Google/Facebook/etc. and pushing humanity forward in some direction.
New tools mean fertile ground for innovation, and VCs are interested in finding and pumping money into fertile ground since they usually have massively outsized returns.
Are they always right? Nope, but Marc Andreessen was around in the 90s, built one of the first web browsers, and co founded Netscape. So if nothing else he’s seen what unrealized fertile ground looks like, and a $4.5B fund signals that he sees it again in the space. Of course a more cynical view is that he purely sees the ability to enrich himself and his fund via pump and dump schemes without caring how it’s done but that’s something that only time will tell I suppose.
