I like NPR's approach to broadcast ads: their own commentators read a short little script, rather than playing an audio clip that was provided to them. There are various ways this can and has been applied to Internet ads, like making them text-only.
On the other side of things, I would love to see a search engine that pushes sites down in its rankings proportionally to the obnoxiousness of their ads.
I dislike this more. I can identify most ads quickly and mute them, while on a network like NPR I might be expecting something, you know, interesting until 20 seconds in I realize it's an ad.
