I always loved this topic on Dipity where you can find the latest Meme things storming the Internet, from the buzz generated by the Blair Witch Project to the moment in which George W. Bush is attacked with a shoe. The last one that caught my attention in the latest days was an initiative launched by my good friend Fer Barbella called "The Ultimate Joker", in which he asks for the Joker character never again being used in any future Batman film, stating that "Heath Ledger is the best Joker ever".

Using the usual kind of 2.0 paraphernalia to support the cause and with a strong concept behind the whole thing, the blog is now visited by more than ten thousand people a day and has been reviewed already in places such as Wired or CNN.

Maybe not advertising per-se but definitely a nice digital phenomenom :)
