@mareklach There's no reason they couldn't.

For hell's sake, I could do that myself. Want to advertise on my website? Gimme a hundred bucks and I'll run your link and up to 500 characters of copy at the top of every page on my site, right under the nav menu.

I could rig that shit up in less than an hour, and it wouldn't require ANY javascript.

If I can manage it, there's no excuse for Google to be unable to provide dumb ads.
