A post at the law blog Balkinization observes, “The fictional high school chorus at the center of Fox’s Glee has a huge problem – nearly a million dollars in potential legal liability” for crimes like performing “a near-exact copy of Madonna’s ‘Vogue’ music video.” Andrew O’Hehir points out that the show “is itself an example of a new business model for generating revenue from popular music … Glee is a music business revenue machine. The cast spawned 25 Billboard top 100 singles in 2009.”
