With a bang-on finale after seven seasons "Young Sheldon" hit nearly 9 million viewers, labeled as the biggest episode in four years of the series' run on CBS. 

In a star-studded finale, the "Big Bang Theory" spinoff bid farewell with a double-header event that left fans on the edge of their seats. The very best episode titled "Funeral" aired at 8pm garnered an audience of 8.8 million viewers – followed by "Memoir", the series finale, which accumulated an impressive 8.95 million viewers. 

Notably, "Memoir" became the heyday of CBS's most substantial non-sports Thursday night.  This marked a significant 28% increase compared to the viewership average of Season 7 up to that point. All data referenced is based on Live + Same Day figures from Nielsen.

The closing of the spinoff series also witnessed a notable leap in livestream viewership. CBS reported a remarkable 39% increase in live views for "Young Sheldon" across Paramount+, CBS.com, and the CBS app compared to the preceding week, with an even more impressive 50% spike compared to the Season 6 finale.

The momentum didn't halt there — episodes of "Young Sheldon" continue to experience growth in delayed viewing, with Season 7 averaging a substantial 13 million viewers when factoring in 35 days of viewership.

The years of remarkable ratings topped off with Thursday night achievements for the "Big Bang Theory" spinoff. Since its premiere during the 2017-2018 broadcast season, it swiftly claimed the title of the most-watched new comedy. Following the closure of "The Big Bang Theory", it ascended to become the paramount broadcast comedy during the 2019-2020 season.
