Yeah, his comment was quite unpresicise, but the entertainment aspect of computing has helped driving development; be it hardware/software and the web.
Today you have millions upon millions of people spending alot of money yearly on hardware they dont really need, just do to get max performance with max visuals.
Take a look at Twitch.tv. The viewer count there has taken off quite a bit lately, people watching streamers and prize money competitions.
Some of the Esport events got massive 1st place prizes and its not slowing down.
As for youtube. Lately its become quite heavy on the adverts. I do realise it cost alot of money to maintain, but if they add much more between each stream, it might start to loose popularity (with me atleast

)
