A nice idea from Austria: produce a shitty TV ad aimed at people <30 and then ask them to make it better (which is the translation of the URL: Machsbesser.com
You have to send in your script or a little clip, and if you win, you get to participate in the professional production of your own spot.

Unfortunately this is in german, so some might not be able to understand it. But basically, the big boss at the client hates the ad (and that’s no surprise), all the others have their typical klischee roles of nodding or justifying. Quite funny – but all in all it reminded me somewhat of „truth in advertising“ – sorry can’t find the URL to that one just now…but I guess you have seen that one already, it’s been around for quite some time.
