This week's Britney Spears-themed episode of Glee, its second of Season 2, earned itself a 5.8 adults 18-49 rating. That number is a series high for the show, and makes it Fox's highest rated Fall live-action comedy broadcast in eight years in the adults 18-49 demo.
This series is showing no signs of slowing down, and so far has avoided the sophmore slump many other shows suffer.
