Two things seem to be at work. The first is the incredible desire people have to share video clips with each other. That’s now apparent.
What’s not so apparent, unless you actually have tried to use the various video sharing sites, is that nobody — and I mean nobody — made it easy until YouTube.
By merely combining a pent-up demand with ease-of-use you get the YouTube phenomenon. It’s brain dead simple, but I’m telling you that is all there is to it.
The hardest part of the process is the user managing to get the video onto a computer where it can be uploaded to YouTube. Nowadays with digital camcorders and still cameras that shoot .MOV files it is not that hard and most cams come with software to make it easier.
Then comes YouTube. The first thing you notice about YouTube is the lack of barriers to entry. You can sign up quickly and upload anything in any format right away.
