As midseason replacements and limited event series continue to populate the primetime lineup, last night saw an ending of sorts. With a pregnancy and a declaration of love, The Mindy Project (0.8/3) wrapped up its third season. There has been no announcement of a Season 4 for the Mindy Kaling-created and starring series from Fox but this finale certainly took a tumble among adults 18-49. In preliminary numbers, the 9:30 PM sitcom hit a series low last night. Year-to-year, Tuesday’s Mindy Project plummeted 38% among the demo from its Season 2 ender of May 6 last year.

Though up a small 3% in total viewers to 2.1 million, last night’s TMP was down 11% among the 18-49s compared to its March 17 show. It is worth noting that last week’s TMP was preceded by a New Girl repeat just like last night’s episode was. In fact the only other new show on Fox last night was Hell’s Kitchen (1.3/4) at 8 PM, which was even with its March 17 airing.

With that ending, there were also some almost new beginnings on primetime last night – though they all took a double-digit plunge from last week’s premieres. NBC’s blended family comedy One Big Happy (1.2/4) fell 25% from its decent March 17 debut while The CW’s iZombie (0.7/2) was down 13% from its series opener. Didn’t help that the latter’s lead-in The Flash (1.1/4) lost its stride 15% from last week to hit a low in the demo in early numbers – though the young adult superhero show from WB TV does sometimes pick up in later numbers, so don’t call that race yet.

One Big Happy also didn’t have any lead-in favors with the second week of the second season of Undateable (1.5/5) down 21% and its lead-in of The Voice (2.7/9) falling 16% from its March 17 show to match a season low in preliminary numbers. Being that the Mark Burnett-produced singing competition show commonly sees some bounce in later numbers, that early result certainly has a chance of changing for what was still the top-rated show of the night. NBC’s primetime ended with The Night Shift (1.03) in a special Tuesday slot. They might want to ask for another shift as the slot saw the show down 33% from its March 24 performance at 10 PM and down 38% from what Chicago Fire drew in the same time period last week.

The Voice was tops among the key demo but NCIS (2.2/7) was far away the most watched show of Tuesday’s primetime The Listwith 16.01 million tuning in for the procedural. Even so, NCIS was even with its last original of March 10 and matched a season low in early numbers. The same could not be said of its spinoff NCIS: New Orleans (1.9/6) – in a good way. The Big Easy-based show was up 19% over its last new show of two weeks ago. NCIS: NOLA also saw a 13% rise in viewership over its last original to 14.25 million. With those kind of audience numbers, and Person Of Interest (1/5/5) matching its March 10 show in the demo but with 9/19 million overall watching, CBS won the night among total viewers with an audience of 13.153 million. The network also inched ahead of NBC’s 1.7/6 rating to take Tuesday night among the 18-49s with a 1.8/6 rating.

Over on ABC, ratings gravity seemed to be truly at work with every show down to some extent or another. Fresh Off The Boat (1.4/5) and Repeat After Me (1.0/3) were down 13% and 9% from their last originals of March 10. A revelationary episode of Marvel’s Agents Of S.H.I.E.L.D. (1.5/5) slipped 6% from last week’s show while Forever (0.9/3) was down 10% from its last original of March 3 to tie a low in preliminary numbers.
