Dead @ anyone paying for this and not realizing AdBlock exists.
With Hulu, if you use AdBlock it will just show you a black screen telling you to disable AdBlock for the amount of time the Ad was going to play. YouTube will probably use this strategy.
I've seen that they have a "Try Ad-Free" [or something like that] button under certain videos. I couldn't help but laugh. I can't tell when was the last time I saw an ad before a video on YT
