"Medium"

CBS has canceled long-running drama series Medium.

The network is axing the five-year-old thriller, which has been a weak link in its Friday night lineup. RELATED: Another TV show that bit the dust.

Series creator Glenn Gordon Caron announced the news online: "It's true. Allison Dubois will dream her last dream on Fri 1/21. In what we believe will be a series defining episode, Allison and her family will stare destiny in the eye. And destiny will not blink." PHOTOS: Hollywood's most promising young stars.

The most recent Medium pulled 6.8 million viewers and a 1.4 adults 18-49 rating. That's still better than several other non-CBS shows on Friday, but after several years a scripted drama carries a higher production cost that rasies the bar to continue.

CBS rescued Medium from cancelation after NBC axed the program last year, but the writing was on the wall when last month the network declined to pick up the show's back nine episodes for the season.
