This is the time of year TV execs decide what’s going to make their schedules next season. “This year, however, a dark horse has charged onto the TV scene: animation, a genre that to date has provided some of the edgiest and most sophisticated shows on TV.

Just as “The Simpsons” essentially saved Fox Network 15 years ago, animated cartoons could become the small screen’s pinch hitters, even if they’ve been benched for a while.”
