I find it fascinating that, with all the talk about new and creative ways to do ad business, the only ads that I find myself interested in are Youtube ads, which are, in some way, a very old school and tv-like technique.
I tune out ads on Google search, on websites, and ads on Facebook are about as relevant to me as the spam I get in my inbox ([0]). But, on Youtube, I'm stuck with them, so I might as well try to enjoy them. The fact that they are somehow relevant also helps.
[0] Facebook (or advertisers) seems to infer that if I'm in Sweden, I'm interested in ads in swedish. That's kind of unfortunate. Plus, even ignoring that, just like spam, half of them are just referrals to AdultFriendFinder or the likes.
