This fascinating banner ad, or better yet, commercial for the French ISP Club Internet, takes rich media advertising to its extreme. No longer bound by common ad formats, this ad brings total destruction the website it’s showing on (and advertising for).

Via the Dutch blog MarketingFacts, I came across a similar ad for HP, which literally turned the whole site of Emerce upside down. The ad reads: HP has turned IT upside down, it’s time to run your IT as a company. Not a particularly strong line or concept in my opinion, but the end result, a website upside down, is kind of fun.

On TV.com, you notice that they occasionally change the background image and show matching ads for a season premiere of a certain TV series.

And then I start wondering: If the price is right and/or the ad is original, will publishers lend their websites to advertisers and allow them to change or even mess up the site completely? Although such ads are generally considered to be extremely annoying, are we witnessing a new form of pushy online advertising here?

For those of you who enjoyed the Le Duel campaign as much as I did, here’s a link to the original Animator vs. Animation videos by Alan Becker which must have insprired the people behind Le Duel.
