Hollywood trades -- Variety, The Hollywood Reporter and Deadline Hollywood Daily -- are reporting that Fox has canceled the Pittsburgh-set sitcom "Back to You" after a single season.

That decision comes as a surprise. Fox renewed lead-in sitcom "'Til Death," even though it got lower ratings. "Back to You" regularly improved on the household ratings of its lead-in.

Despite some midseason tinkering with the cast -- one actress was let go, another role recast -- Fox seemed high on "Back to You," which starred Kelsey Grammer and Patricia Heaton, was created by Steven Levitan and Christopher Lloyd and was directed by James Burrows. The trades suggest it was those marquee names on-screen and behind-the-scenes that pushed the show's cost up to a point that even its ratings superiority relative to "'Til Death" no longer mattered.

No comment from Fox. I'm attempting to reach Levitan, but not optimistic that he'll be eager to talk about the cancellation.
