Video content creation wasn't a thing that far back.

YouTube was (in my experience) the first site at all where you could click a video and not wait 3 years for it to load, plus having a UI around it.

Most people's Internet speeds weren't even close to being fast enough to consistently load them fast enough to want to watch more than a few in a session. Decent waits and buffers throughout still made it painful. Just less painful than it was before.

Most other videos back then were scattered around on separate sites, and related to the content on the site, and they usually had to download completely before even starting to play. (Kinda like pirating a movie these days)

So given that most people couldn't use other sites and tolerate it for long, YouTube created a market that didn't exist before, and there wasn't a content creation machine in place ready to go.

That kinda took off as more and more people got broadband connections and started being able to watch almost as soon as they clicked a link.

I don't have hard dates for this, just an impression from memory of the era.

So the "creators" were just random people filming slightly less random things. There weren't well known channels, or filters for different genes or topics. You could choose from "dude filming an animal do something funny" or "something unlikely to be caught on camera being caught on camera".

And most of it was shot on terrible cameras (since digital cameras were still going from "looks like objects filmed through 4 layers of plastic" to "really tiny footage of decent quality", there wasn't much that existed to draw a lot of people other than a feeling of hoping to stumble on the newest really cool clip.

But, since capitalism exists to make everything worse, the market got its act together shortly after. But not immediately. It took a whole new kind of infrastructure to get it moving.

People needed better digital cameras (unless you thought transferring from analog tapes was a fun weekend), better Internet, and the site itself has to start figuring out how to run things to make a better experience.

Google buying it was both a great infusion of capital to help it as well as being a cancer injection that would poison it.

I like the concept of peertube, but it's not gonna take off in its current state. I don't think anything takes off without capitalism happening to it these days. If something takes off, it's probably fruit of a poisonous tree. Can't have any good new popular technology without it being tampered with by billionaires
