Sesame Street is about to break standards for television shows that've been on for 45 seasons. Not that a lot of shows have been on for that long, of course. But here the Sesame Street show is prepared not to go off and fade away, but to grow. Signing a deal with HBO, Sesame Workshop has promised five seasons to HBO with "almost twice as much new content as previous seasons." This content will be "exclusive" to HBO for nine months after each episode is aired, after which PBS will be allowed to show reruns for free.
