Over in the U.K., a re-run of a Harry Potter movie scored better ratings than Live Earth:

ITV1′s Saturday night line-up proved more popular than Live Earth for much of the evening, with a repeat of movie Harry Potter and the Philosopher’s Stone watched by 3.5 million viewers and attracting a 26% share between 4.50pm and 7.30pm.

I assume the Guardian has a misprint here and that Hogwarts wasn’t turned into philosophy school* when we weren’t looking.

CORRECTION: Thanks to all who wrote in to remind me that “Philosopher’s Stone” was changed to “Sorcerer’s Stone” for U.S. readers. By any other name, Potter’s still more popular than Live Earth.
