That one include digital videos, which they say includes cable and spot TV (I assume based on the article that this mean streaming sites and sport commentators?). Thus We are now trailing far far away from ads on a website which is the primary purpose of ad-block. TV and by extension video is basically never PPC or PPI based for their advertisement model.

For better statistics, lets pick advertising companies that only offer banner and text ads (like ad-word), or which has clear way to separate them. We also want the number of sites that use each type of model and not the total revenue for the ad company. I am not the least surprised that video streaming, sport channels, and news papers has a much larger revenue source for ad companies than say all other type of websites combined. Feel free to point to statistics that proves this wrong.
