>because they seem harder to block by ad-blockers and thus think that more people will watch them.

Do companies actually believe this? Flash is the easiest to remove of all ads.

  "If you create a truly brilliant ad which is targeted to 
   the right audience and let them do something with your 
   brand inside the ad for example people are more willing 
   to view them in my opinion in stead of just forcing them 
   the same old banner over and over again only with a 
   different brand in them."

I have a lot of sympathy for the outreach companies trying to make advertising agencies behave. At some point, someone's neurons started firing and realized consumers had taken control over how they view media. Someone realized that eventually advertisements were going to be viewed of the users volition. Which meant they no longer could be deceitful, obnoxious, baiting, terrible, and rude. Or at least not transparently so.

Unfortunately the industry was built on the grounds that the users had no choice, so the notion of good advertising I think will never come. Old men in stuffy suits don't change unless they go bankrupt.
