In an expected move that underscores Fox’s struggles in the half-hour arena, the network has downgraded the Sunday timeslot of recent addition “Cooper Barrett’s Guide to Surviving Life.”

Starting April 3, “Cooper Barrett” moves to 7:30 p.m. ET/PT in a time-slot switch with “Bob’s Burgers,” which will now air regularly in the higher-profile 8:30 time period. “Burgers,” now in its sixth season, will also air a second original episode at 9 that night. Through March 13, “Bob’s Burgers” was averaging a 1.3 in adults 18-49 and 2.8 million total viewers in Nielsen’s “live plus-3” averages.

The live-action “Cooper Barrett,” which premiered Jan. 3, has averaged a 1.2 rating in adults 18-49 and 2.8 million viewers (L+3) in the 8:30 p.m. half-hour between long-running animated hits “The Simpsons” and “Family Guy.” It fell in its final 8:30 p.m. airing last week to a 0.8 in the demo and 1.95 million viewers in same-day averages and saw only minimal lifts in L+3 (to 0.9 and 2.1 million).

Earlier this month Fox moved another underperforming new Sunday comedy, “Bordertown,” to the 7 p.m. half-hour. It pulled a mere 0.8 in 18-49 and 2.2 million total viewers in L+3 for its first airing there on March 13.

The move of “Bob’s Burgers” to 8:30 p.m. should help maximize ratings for Fox’s stronger Sunday comedies, which will now air as a two-hour block from 8 to 10. Among them is sophomore “The Last Man on Earth,” which remains a good performer in time-shifted viewing; last week it posted the largest percentage lift for any of the Fox comedies across the week’s schedule (+45%, 1.07 to 1.55 in 18-49).

The net has failed to gain much traction on Tuesdays with new comedies “Grandfathered” and “The Grinder.” In season-to-date L+3 averages, the former is averaging a 1.3 in 18-49 and the latter a 1.1.
