It was cancelled after the initial run of 13 episodes is over.
" For Murphy Brown, the rebooted series was always intended to be a closed-ended order of 13 episodes. The multicamera comedy, featuring the return of star Candice Bergen and from original creator Diane English, has underperformed (6.2 million total viewers and a 0.9 in the key 18-49 demo) in its prime Thursdays at 9:30 p.m. slot and remains in consideration for a renewal. Fellow multicamera comedy Fam, starring Nina Dobrev and Tone Bell — which has already changed showrunners — will take over Murphy Brown's slot starting Thursday, Jan. 10."
