The four networks are poised to increase this season's sitcoms displayed prior to May 1 to 36-37 entries planned vs. last year's 34. All debut dates, save for FOX's Brooklyn 99, NBC's Trial & Error, are slated between February 1 and April 10. Several shows will dip in and out of the schedule between now and then, so let's look at what 2018's calendar offers:
COMING:
February 1: The same evening The Good Place bows out for its 2nd season, AP Bio makes a special debut behind Will & Grace. Following the frosty Olympics, it is slated to return March 1.
February 26: CBS debuts its 10th entry of original programming in the 9:30 timeslot, which has not housed a successful occupant since spring 2014 with Mike and Molly. Can this sitcom produced by Johnny Galecki break the network's curse over this troubled timeslot?
March 8: NBC announced on January 9 that Champions will debut on March 8, presumably in the vacated 8:30 timeslot used by The Good Place. Champions has 4 weeks of mining Will & Grace as its leadout, an ideal setup crafted by NBC.
March 27: Aided by a 60-minute premiere, Roseanne returns to television on ABC after a 21-year hiatus. Can the reincarnation ignite a fraction of the original series' ratings magic? After all, Roseanne was a top-10 player for 7 of its 9 seasons. And on this same evening, ABC launches its latest pilot, Splitting Up Together in the cursed 9:30 timeslot. Can the series survive a timeslot which has claimed the short existences of The Real O'Neal's, Imaginary Mary and The Mayor? Hopefully, a lack of competition from NBC's powerhouse This is Us, as well as a rumored March rebound for the network can keep this series above the 1.0 mark for a fighting chance.

April 10: After six critically-heralded seasons, New Girl bows out of the FOX lineup with an 8 episode run. Which timeslot remains unclear, but it will likely be paired with Brooklyn 99 and/or the remainder of The Mick's 20-episode season.
GOING:




GOOD AS GONE:
January 25: It appears Great News is slated to conclude its run early as 10 episodes of the 13-episode run have already played out. The sophomore series, which received a surprise renewal last year after averaging a 0.80 rating, has already dropped below that average at 0.79, currently ranked 28th among the 29 sitcoms. It's broadcast range has scattered ratings between 0.4-1.3, heavily dependent on its strong lead-in, Will and Grace. Will it survive the season? Currently, it is NBC's weakest sitcom.

ALREADY OUT:

October 30, 2017: The season's first Monday minus The Big Bang Theory created a fractional bloodbath, with Me, Myself & I collapsing and tying the network's sitcom low at 0.7. CBS shelved the series as it finished with a 1.00, shuffled 9JKL into its 9:30 deathslot to open the 8:30 timeslot for returning Man With a Plan.
December 12, 2017: Although the 9th episode of ABC's freshman series ticked up during an evening of rebounds, it meagerly managed a 0.8 rating. It was MIA as recently as January 2, being replaced by a Modern Family rerun. ABC yanked the series on January 4 after it averaged a 0.82, currently finishing the season ranked 26th of the 29 sitcoms.

MIA:
NBC's debut of Trial & Error has yet to declare a debut timeslot. Brooklyn 99, which stands in last place among the 29 sitcoms on the air with an abysmal 0.65 average, has yet to have a date and timeslot declared to finish out the season.
