According to Nielsen ratings, "Watch While I Revise the World" was watched by 8.63 million viewers and held 2.8 rating/7 share among viewers between 18 and 49 years of age.
The episode was outperformed by "Sunday Night Football" on NBC, which averaged 22.05 million viewers and a 8.9 rating/22 share, "The Good Wife" on CBS, which was watched by 10.28 million viewers but held a 2.1 rating/5 share and "Family Guy" on Fox which was watched by 6.99 million viewers and held 3.5 rating in the 18-49 demographic.
This episode was the least watched episode in terms of total viewers in the history of the show until the air date of next episode, School of Hard Knocks, although the episode was the most watched scripted program of the night in the 18-49 demographic.
The episode gained an additional 2.0 million viewers and 0.9 rating in the week following the original broadcast due to DVR recordings. 
The episode was viewed by 7.11 million people with a Nielsen Rating of 3.2/8 and came in second on the Animation Domination lineup slightly behind "Family Guy"'s "Business Guy" which had 7.68 million viewers and was second in its timeslot.
"The Simpsons" was the third most viewed episode on Fox, after "Family Guy" and "Bones".
The episode was 3rd ranked on Fox in the 18-49 rating after "Family Guy" and "Glee" and made it at 21 in all.
IGN's Robert Canning gave the episode a 7.6/10, saying "The episode did well by sticking to one main story instead of adding a weaker "B" storyline to fill the half hour."
When "Futurama" debuted in the Fox Sunday night line-up at 8:30 p.m. between "The Simpsons" and "The X-Files" on March 28, 1999 it managed 19 million viewers, tying for 11th overall in that week's Nielsen ratings.
The following week, airing at the same time, "Futurama" drew 14.2 million viewers.
The show was then moved to Tuesdays at 8:30 p.m. "Futurama"'s first episode airing on Tuesday drew 8.85 million viewers.
Though its ratings were well below "The Simpsons", Futurama's first season rated higher than competing animated series: "King of the Hill", "Family Guy", "Dilbert", "South Park" and "The PJs".
When "Futurama" was effectively cancelled in 2003 it had averaged 6.4 million viewers for the first half of its fourth broadcast season. 
"Touch" debuted to over 12 million viewers in the pilot episode, with the next episode pulling in more than 11.8 million.
But ratings fell sharply after that, and the season one finale garnered just 4.6 million viewers.
After the first two episodes of season two, all of the remaining 11 episodes fell short of 3 million viewers, leading to the series cancellation. 
The episode was watched by a total of 3.77 million viewers, making it the second lowest-watched episode of "The Simpsons" ever after Diggs.
In part, this was due to pre-emption by the Sandy Hook Elementary School shooting memorial service, which aired live on many East Coast markets.
The show still managed to be Fox's most watched show of the night.
That night's new episodes of "Family Guy" and "American Dad!"
episodes ("Jesus, Mary and Joseph!"
and "Minstrel Krampus") were preempted and replaced with reruns of their respective shows ("Grumpy Old Man" and "Wheels and the Legman in: 'The Case of Grampa's Key'").
Fox decided to repeat "To Cur with Love" in the regular timeslot one week later replacing a repeat, while also putting the pre-empted episode of "Family Guy" and a new episode of "American Dad!"
entitled "National Treasure 4: Baby Franny: She's Doing Well: The Hole Story", unrelated to "Minstrel Krampus", on the air.
The repeat was watched by 4.89 million viewers with a 2.1 rating in the 18-49 demographic.
This made it the 3rd most watched show in the Animation Domination line up that night, losing out to "Family Guy" and a "Simpsons" repeat of "Gone Abie Gone".
