YouTube has definitely become more and more ad-ridden since its inceptions, and the ads are definitely personalized (though badly). There are now videos with multiple ad interruptions, a bit like ye olde TV. I do think one difference here is that on YouTube, if a video is full of ads, I won't keep watching long unless the content is solid and interesting. I, as a watcher, have a choice as to what I watch. Though of course, YouTube could fix that by imposing the same amount of ads on all videos.
