Fox has renewed perennially low-rated science fiction series Fringe for a 13-episode fifth and final season, an order that will, conveniently, bring the series to exactly 100 episodes. That should be a boon to the series’ studio, Warner Brothers, as it attempts to sell the show into syndication or a cable rerun deal. The renewal had been expected by most TV industry watchers, and it’s also heavily suspected that Warners cut Fox a substantial deal on the show—which Fox president Kevin Reilly said the network loses money on at January’s Television Critics Association press tour—in order to keep it on the air. The 13 episodes will apparently wrap up the series’ ongoing storyline about the conflict between two universes, a storyline that has won the series much fan and critical adoration but has most likely kept it from mass audience appeal.
