The first game of the World Series delivered a ratings win for Fox on Tuesday, but it fell short of last year's opener. Regular programming on other networks was mostly unaffected, with NBC's This Is Us and several other shows actually improving week to week.

The Washington Nationals' 5-4 win over the Houston Astros in game one of the World Series averaged 12.19 million viewers for Fox, adjusted up from 11.58 million in the fast nationals. Tuesday's audience is the lowest for a World Series opener since 2014 (also 12.19 million) and is off by 11 percent from last year's 13.76 million viewers.

In Houston, the game drew a 34.1 household rating, while it delivered a 23.1 in Washington, D.C.

This Is Us scored a 1.6 rating among adults 18-49 and 7.06 million viewers, up from 1.5 and 6.72 million for its initial airing last week. New Amsterdam (0.9, 5.13 million) had its best 18-49 rating since premiere week, and The Voice improved a little in total viewers to 8.07 million while holding at 1.3 in adults 18-49. (This Is Us and New Amsterdam more than double their same-day ratings with a week of delayed and digital viewing.) 

CBS' NCIS (11.34 million viewers, 1.1 in adults 18-49), FBI (8.87 million, 0.8) and NCIS: New Orleans (6.64 million, 0.7) all grew a little in viewers over last week while holding steady in adults 18-49. The same was true for The Flash (1.38 million, 0.5) on The CW. Arrow was steady in the 18-49 demo at 0.3 but fell a little in viewers to 773,000.

ABC's Mixed-ish and Black-ish each posted a 0.7 in adults 18-49, up a 10th of a point each over last week, and improved a little in total viewers as well. The network also aired specials It's the Great Pumpkin, Charlie Brown (1.3 in the demo, up from 1.2 in the fast nationals), Toy Story of Terror (1.0) and news special The Douglas Dynasty (0.5).

Fox topped the night in adults 18-49 with a 3.1 rating. NBC had the best non-sports rating at 1.2. CBS (0.9) edged out ABC (0.8) for third place. Telemundo came in at 0.5 and The CW and Univision tied at 0.4.
