No one likes ads.  Or well, I thought I didn't.  I actually considered myself  at one time to be an individual that was immune to commercial offers and recommendations.  This however has changed with the crafty advent of Youtube ads.  I don't know what it is, but I can watch TV all day and won't notice a single ad that plays, much less be interested.  YouTube however shows me multiple ads worth watching every time I go on.  After giving it some thought, I see some differences that explain YouTube's effectiveness.  With YouTube, you get an ad of some sort every time you click on a video, this leads to more frequent ads and thus there is more likely one that I will want to watch, the ads are also controlled by what you have been searching with Google.  This is probably the most prominate reason for my interest.  If I've been looking up woodworking all day, then YouTube is going to show me an ad for Delta power saws.  Cable TV can't do that.  There is also the aspect to YouTube knowing your age.  If I have a Youtube account, then YouTube knows if I'm old enough or not for some more mature, comedic ads that would never make it to television.  I've seen some ads that made me literally laugh out loud, but then again I would sit and think wow, they're pushing it with that one. It's interesting as well, that when watching a movie trailer with YouTube, your prompted and often successfully lured into watching a full second one before you watch the one you wanted.  You get twice the trailer for just the one click.  Seeing all this it's got me thinking, does YouTube exist for the videos or for the ads.  Yep, that ones a no brainer.  Looking at YouTube from a marketing standpoint and its a gold mine. No wonder Google's so rich.
