NBC has issued an early renewal for its Wednesday night drama Medium. This will be the fourth season for the Patricia Arquette series. Though the series does not usually win its timeslot, it does typically build on its lead-in Crossing Jordan in the key 18-49 demographic.

NBC Entertainment President Kevin Reilly stated, “Medium is a quality show with an outstanding star that has always delivered a very loyal audience. We are pleased to know that we can look forward to more of its unique storytelling next year under executive producer Glenn Gordon Caron’s superb creative vision.”

It’s unknown as yet how many episodes the peacock network will order or if Medium will be held back as a midseason replacement (as was the case this season). NBC ordered six advance scripts a few weeks ago, likely in an attempt to plan for a potential writers’ strike in the Fall. Their schedule plans will likely be influenced by that possibility as well. The network announces its 2007-08 schedule next week. Any predictions? Stay tuned!
