Be interesting to compare with how prevalent the different ad types actually are, how effective they are, and how much money they typically cost. Preroll video may be more "annoying" than Related Links ad units, but they also pay a LOT more and are probably more effective any way you measure it.
That comparison would have been great. Annoying ads is one thing, but how effective are they? Modal ads can be really annoying, but some marketers claim that they are highly effective, especially for building a mailingist. Or do we hate some ad types because they are very effective?
Do you know any very effective ad type ? I don't even know an effective commercial ad (maybe the 30 seconds TV spot?).
