According to The Hollywood Reporter, CBS is looking to pick-up Medium as the show's talks of renewal with NBC have gone stagnant.

Apparently, NBC isn't giving Medium the respect that it deserves considering how long it is has been on the air. Also, NBC and the show's producer are having a tough time agreeing on "the license fee and the size of the order" for the show.

Lastly, the conglomerate that owns NBC has a lot to gain by increasing the number of episodes made, which would boost the series' syndication revenue.
