ABC’s ‘The Rookie’ Prepared Ahead for Season 9 Cancellation

First responder and procedural dramas have long been among the most enduring genres in network television. They've shown remarkable longevity, with many series running for well over a decade while maintaining loyal audiences. But even that kind of track record is no guarantee of survival. As networks continue to reevaluate their schedules and make room for new programming, even established hits can find themselves on the chopping block (case in point, CBS' Blue Bloods). While it's been a relatively good year so far in terms of cancellation news, one of television's biggest long-running cop dramas perceived the possibility that it could be canceled after nearly a decade.
