More trouble for San Francisco-based “Current,” the twentysomething news network founded by former vice president Al Gore and legal services millionaire Joel Hyatt of Atherton. A month after it was sued by a Maryland Internet company for using the name “Current,” it has been hit by a second lawsuit, this time from Minnesota Public Radio, which also claims it owns the name “Current.” Meanwhile, a blog called NewsBusters (its slogan: “Exposing and Combating Liberal Media Bias”) points out that the network has a “Tipper-shocking appetite for raunch,” including one program during which “women loosened up by tequila suck on lollipops as they muse about their sex lives.”
