It’s been a long time coming, but CBS has formally announced the cancellation of Medium. Currently in its fifth season after moving to CBS from NBC, Medium‘s ratings just weren’t strong enough to justify the rising production costs of the show.

CBS will air the show’s final episode on Friday, January 21st.

Also in cancellation news, TNT has pulled the plug on Dark Blue. Likewise citing low ratings, TNT decided that 2.2 million viewers per episode simply wasn’t enough to save the Jerry Bruckheimer-produced drama about undercover cops. Dark Blue just aired its second season finale in September.
