I think you mean "why is everything online so long-winded". Geez, look up any video on nearly anything simple, they all follow the same format:
* 10 mins of nonsense and irrelevant background into how great you are
* 10 mins of setup
* 10 mins of drama build-up
* 1 min of the actual event
* 10 mins of closing comments
Oh, wait, I forgot, it is not about the content, it is all about how long I can get you to watch so I get more nickels. Dang, now I made myself sad...
