In another example of how much viewing of a scripted series takes place after its regularly scheduled episode, last week’s episode of FX’s “The People v. O.J. Simpson: American Crime Story” more than doubled its same-day delivery of young adults in just three days to vault to a No. 1 ranking among all programs for the night.

According to Nielsen’s “live plus-3” estimates, the season’s second episode of “The People v. O.J. Simpson” averaged a 3.07 rating in adults 18-49 and 7.42 million total viewers — surging 103% in the demo and 48% in overall audience from its same-day ratings (1.51 and 3.89 million). As a result, a same-day decline of 23% was trimmed to just 6% (3.07 vs. 3.27) in L+3. And of course, this decline could disappear — or even flip to the plus column — when all viewing is registered in approximately 60 days.

The FX anthology series ranked No. 1 among all Tuesday series in L+3 demo rating, moving ahead of five shows that had beaten it in same-day: “NCIS” (3.04 in L+3), “Chicago Fire” (2.55), “NCIS: New Orleans” (2.38), “Chicago Med” (2.24) and “The Flash” (2.23).

Week-to-week in L+3, “The People v. O.J. Simpson” held steady in adults 18-34 rating (1.87) while growing in all three men demos: men 25-54 (up 4%), men 18-49 (up 3%) and men 18-34 (up 13%). Of these categories, it stood as Tuesday’s No. 1 program on television in adults 18-34, men 18-34 and men 18-49, and was a close second to CBS vet “NCIS” in men 25-54.

According to FX, the L+3 delivery for the first two episodes of the series “illustrates the increasing irrelevance and incomplete picture of Live+Same Day rating compared to the ultimate viewership of an FX original series and most scripted entertainment programs.”

“The People v. O.J. Simpson: American Crime Story” continues its 10-episode season tonight. The series has garnered universal acclaim from critics and currently ranks No. 1 of all series in 2016 on Metacritic with an average score of 90, and is 97% Certified Fresh on Rotten Tomatoes.
