Well we all know that the success of the Harry Potter epic has spawned a million knock-offs. No dollar store is complete without a non-trademark-infringing "Wizard Dress-Up Kit" consisting of a plastic wand, glasses, and rubber scar.
It's spawned protests by the evangelical Christian equivalent of the Michigan Militia (my guess is that at least 100,000 Potter books were sold to people taking them to the weekly burnings)
And now ... a new genre of music. Called Wizard Rock, also known as "Wrock", it's apparently a hot new thing among the late-teens.
Almost 500 groups call this new genre home. Some of the bands on the scene:
Harry and the Potters: the originals, apparently.
The Nifflers: A 17-year-old geek and his 13-year-old sister. Read here the interview by the National Post, Canada's newspaper Death Eaters to Harper's Voldemort. And speaking of the which, or possibly witch:
Voldemort: Wizard metal, would you believe?
Well, presumably Dumbledore did.
