The show's twenty-two Emmy nominations in 2009 is a record for the most nominations a comedy show ever received in a single year.

Alec Baldwin has said that this show was the best job he's ever had.

Liz Lemon's catchphrase "I want to go to there" was coined by Tina Fey's daughter Alice.

In the early episodes, it is revealed that Liz Lemon had won one Emmy, just like Tina Fey had at the time this show debuted.

One of the reasons Jane Krakowski (Jenna) was drawn to the series was because it gave her the chance to sing and dance. Modern sitcoms don't usually allow for that; this was the first since Ally McBeal (1997).

Influenced by creator Tina Fey's experience while being head writer for Saturday Night Live (1975).

Tina Fey was not originally going to star on the show. However, NBC insisted she appear.

In her 2011 book "Bossypants", Tina Fey said that during the early years of the show, Donald Glover was its only black writer. She also said that he was so young that when he started on the writing staff, he was still living in a New York University dorm, and working there as a Resident Adviser. Since he came from a large family in Stone Mountain, Georgia, Fey said that Glover was especially good at writing for the character of Kenneth, who was also supposed to be from Stone Mountain. Glover later became a star on Community (2009).

Alec Baldwin won the SAG Award for Outstanding Actor in a Comedy Series every year since the show's inception until 2013, a feat held by no other actor in either drama or comedy. In addition, he won another one in 2009 as part of the cast. He was also nominated for the last time in 2014, but failed to win that time, probably because the show ended in January 2013.

Tina Fey wrote Kenneth Parcell with Jack McBrayer in mind to play him.

Jeff Richmond, Tina Fey's husband, composed all of the show's music and later served as a producer and guest director. He also appeared on screen as a "TGS" musician in several episodes.

Jon Hamm auditioned for the role of Jack Donaghy. He appeared on the show as Dr. Drew Baird.

Tina Fey had to leave Saturday Night Live (1975) in order to appear in the show as the schedules overlapped. Rachel Dratch also left the show at this time, as she was set to play Jenna DeCarlo. After appearing in the first version of the pilot, Dratch was replaced by Jane Krakowski and given bit parts during the first season.

With the exception of Jenna, Tina Fey wrote the main parts for the cast members playing them.

In 2012, Tina Fey explained the Emmy on display in Liz Lemon's office: "I've always sort of thought that it's a Daytime Emmy and that perhaps she got it for writing a really specific category, like Best Regional Promo for the show The Mommies (1993) or something like that... (or) for writing jokes for Joy Behar for The View (2001), it's definitely a Daytime Emmy. It's a local Daytime Emmy."

"Elizabeth" is the real first name of Tina Fey, whose full name is Elizabeth Stamatina Fey.

Tracy Morgan had to be written out of a few episodes of season five following a kidney transplant.

Lee, a Costume Designer for "TGS", is played by Tom Broecker, who was a Costume Designer for this show.

Tracy Morgan (Tracy Jordan) and recurring player Rachel Dratch followed creator and star Tina Fey from Saturday Night Live (1975) to create this show. In addition, Alec Baldwin holds the record for the most times hosting Saturday Night Live (1975) (seventeen times as of February 2017).

Tina Fey originally pitched a series about a cable news producer who is forced to produce a show hosted by a right-wing pundit ("Alec Baldwin if we could ever get him", Fey envisaged). Then-NBC President of Entertainment Kevin Reilly instead suggested that Fey use the "write what you know" formula and come up with a show based on her own experiences as the first female head writer of Saturday Night Live (1975).

The professional and personal relationship between Liz Lemon and Jack Donaghy (who considers himself Liz's mentor) is based in part on Tina Fey's real-life friendship with Executive Producer Lorne Michaels.

Liz Lemon's office has a framed cover of "Bust Magazine" with Amy Poehler reenacting Janet Leigh's shower scene in Psycho (1960). Tina Fey and Poehler are close friends, and former cast members on Saturday Night Live (1975).

Tina Fey didn't want Liz Lemon to be a single mother because it would have restricted her character. This allowed Liz more freedom in her life and gave Fey more avenues to explore for plotlines.

Liz and Jenna began "The Girlie Show" at The Second City in Chicago. In 1992, Tina Fey took classes there, and in 1994, was invited to join the cast. Her writing partner was Rachel Dratch, and their time together inspired the relationship between Liz and Jenna.

In an unusual move for a modern sitcom, the show was shot on more expensive film stock, rather than in digital.

The same year that this show started airing, Studio 60 on the Sunset Strip (2006), another show set behind the scenes of a fictional Saturday Night Live (1975)-type show, also premiered. Even though there were many differences between them (including this show being a half-hour sitcom, while "Studio 60" was an hour-long drama), many critics compared the two shows and engaged in speculation about which one would survive. "Studio 60" was cancelled after one season, and Creator Aaron Sorkin and former regular Nate Corddry guest starred on this show.

The show was finally syndicated in 2009, something Tina Fey had always complained about.

On December 29, 2006, Nielsen Media Research reported the results of having, for the first time, monitored viewers who use a digital video recorder to record shows for later viewing. According to the Nielsen numbers, this show had the fifth-largest increase (viewers who use a DVR to record the show and then watch it within a week of its initial airing). According to Nielsen, the show added nearly 7.5 percent to its total audience every week as a result of these "live plus seven" viewers.

Season two was shorter than season one (fifteen episodes as opposed to season one's twenty-one), because of the 2007-2008 Writers Guild of America strike. Season seven was the shortest season, with twelve episodes.

The awning in front of Liz Lemon's apartment has displayed two different addresses over the course of the show. In some episodes the address is 160 Riverside Drive and in other shows the address is 168 Riverside Drive. The former is the real address of the exterior building shown and it is directly across the street from the exterior building used on Will & Grace (1998). In an audio commentary, Tina Fey jokes that they should've shown Eric McCormick (star of Will & Grace (1998)) walking out of that building.

Jane Krakowski and Cheyenne Jackson originated the lead roles in the workshop of "Xanadu" on Broadway. Krakowski left the show before it premiered to appear on this show instead. Jackson decided to leave the show because he did not want to perform without her. He ended up returning when the replacement actor broke his ankle only a short while before the show opened. Both have since appeared on this show together, where their close real-life friendship is reversed, with Jenna resenting Jackson's character and he being disgusted by her constant rude behavior.

In several episodes in season four, there is a picture of Kristen Wiig on Jack Donaghy's window sill behind his desk.

Aside from the main cast and the supporting actors credited at the beginning of each episode (Tracy's entourage and "TGS" employees), the only cast members who appeared in every season are Elaine Stritch, Will Arnett, Chris Parnell, and Dean Winters.

In a 2018 "New Yorker" profile of Donald Glover, Glover said that he had long wondered if he had been hired as a writer on this show because of his race. At the time he was hired, he was only twenty-three-years-old, still living in the New York University dorms as a Residential Advisor, and had limited experience. Tina Fey confirmed Glover's suspicion; she admired Glover's talent, but hired him because funds from NBC's Diversity Initiative "made him free." This set-up was actually a subplot in season four, episode seventeen, "Lee Marvin vs. Derek Jeter", when Toofer discovers he was hired because of NBC's Diversity Initiative, which was still covering his salary.

Alec Baldwin loved Jack's wardrobe so much that he purchased the suits at the end of the series. According to Costume Designer Tom Broecker, Baldwin "wrote a big check to NBC" so he could take the clothes home when the show ended.

Jack Donaghy is a staunch conservative Republican who looks down on anything he considers even remotely liberal. In real-life, Alec Baldwin is a staunch Democrat famous for his loud liberal political views.

The show often pokes fun at themes and characters that the show leaves hanging. For example, in one episode, Kenneth tells Liz that no more mail could fit into her box because it was stuffed with unopened adoption letters, hinting at Liz's efforts in earlier episodes to adopt a child. Another instance is the character of Danny Baker. In one episode, Pete tells Danny that he would've asked Danny to do a favor for him, but he forgot he works at "TGS", poking fun at the fact that Danny often goes missing for several episodes at a time. In the one hundredth episode, Danny states that he remembers season one of "TGS", even though he hadn't worked there yet, but then later in the episode, has Josh's flashbacks, meaning that Danny and Josh share the same fate, in which they both appear in several episodes and then are never heard from again.

Don Geiss and his son Bertram (played by real-life father and son Rip Torn and Tony Torn, respectively) never shared a scene together.

Season three saw an influx of special guest appearances, including Steve Martin, Jennifer Aniston, Oprah Winfrey, Megan Mullally, Jon Hamm, Salma Hayek, and Alan Alda.

Grizz Chapman (Grizz) and Kevin Brown (Dot Com), who played members of Tracy Jordan's entourage, were friends with Tracy Morgan in real-life prior to the show. Brown had once been Morgan's manager.

All the liquor that Jack is seen drinking in his office is actually iced tea.

John Lutz (Lutz) and Sue Galloway (Sue Laroche-Van der Hout), who play writers on "TGS", are married in real-life.

Jenna's name is a play on Janel Moloney (who guest-starred in the series).

Although it was not stated on the show, Katrina Bowden revealed in a 2008 interview that her character's full name is Cerie Xerox. Executive Producer Robert Carlock had created a backstory for her that she was the heiress to the (fictitious) Xerox family fortune, and that her family connections had gotten her the job at NBC.

Before Will Forte played Paul, Jenna impersonator turned boyfriend, he appeared in season one, episode twelve, "Black Tie", as Tomas, the assistant to Hapsburg Prince Gerhardt (Paul Reubens). In the episode, he tells Jenna that the Prince wishes to meet her and introduces them.

Andrea Martin was offered the role of Margaret Lemon, but her commitments to the Broadway show "Young Frankenstein", a musical adaptation of Young Frankenstein (1974), prevented her from appearing. Martin later guest starred as Bonnie Badamath.

Liz Lemon (Tina Fey) says the first line of the series and Kenneth Parcell (Jack McBrayer) says the final line.

Donald Glover, who was a Staff Writer and Script Supervisor for the show from 2006 to 2009, also had brief roles during that period, such as Young P.A. in season one, episode five, "Jack-Tor", or as Gay Kid in season three, episode twenty-two, "Kidney Now!" After he left the show for a role on Community (2009), he returned to play Young Tracy Jordan in season six, episode nineteen, "Live from Studio 6H". During an April 2012 interview with "Entertainment Weekly", Tina Fey said that they already knew that Glover "could sound like Tracy, because we did an extended version of (Tracy Jordan's novelty song) 'Werewolf Bar Mitzvah', and by the time we finished it, we were wrapped and didn't have Tracy. So half of it is just Donald imitating Tracy."

Liz's love interest Floyd DeBarber (Jason Sudeikis) takes his name from Floyd Lawson, known as Floyd the Barber, from The Andy Griffith Show (1960).

In 2010, a blogger calculated that the show averaged nearly ten jokes per minute.

The series was filmed at Silvercup Studios in Long Island City, Queens, New York. Several of the extras and minor characters over the show's run, such as Subhas the janitor (Subhas Ramsaywack), were real employees at Silvercup.

The original title for the show was "Rock Center" before it was changed to "30 Rock". Tina Fey liked the title "The Peacock", but NBC executives did not want the corporate logo to be mocked.

The series was originally going to include frequent sketches from "TGS" as part of the show. After the unaired pilot, it was decided to focus less on the sketches and make it more of a traditional sitcom, which is why Jenna's role was re-cast, with Jane Krakowski replacing Rachel Dratch. Over the course of the series, elements of "TGS" (such as characters in costume and announcements about people being needed on set) disappeared almost entirely.

In season one, Jack (Alec Baldwin) mentions watching Friends (1994) and makes several references to the show. Baldwin made an appearance in Friends (1994) as Parker, the overly enthusiastic man Phoebe dates in season eight. Also, David Schwimmer, who played Greenzo in season two, episode five, "Greenzo", and Jennifer Aniston, who played Liz and Jenna's crazy friend in season three, episode three, "The One with the Cast of Night Court", guest starred on this show.

Tina Fey's oldest daughter, Alice Richmond (born 2005), appeared at the end of every episode in the title card of Tina Fey's production company, Little Stranger, Inc., dressed as a peacock. In the series finale, the title card was updated to include her second daughter, Penelope Richmond (born 2011), dressed in the same peacock costume. Alice also appeared as a young Liz Lemon in season seven, episode seven, "Mazel Tov, Dummies!"

In addition to Tina Fey, Tracy Morgan, Jason Sudeikis, and Rachel Dratch, many Saturday Night Live (1975) alumni were on this show over the years, including Chris Parnell as Dr. Spaceman, the late Jan Hooks as Jenna's mother, Verna Maloney, Will Ferrell as Shane Hunter, Fred Armisen as Frank 2.0, Bill Hader as Kevin, Julia Louis-Dreyfus as Liz in a live episode, Rob Riggle as Reggie, Bobby Moynihan as Stewart Derr, Siobhan Fallon Hogan as Patricia, Andy Samberg as himself, Kristen Wiig as Candice Van Der Shark , Amy Poehler as young Liz, Don Pardo as Sid the announcer, Horatio Sanz as Maynard, Molly Shannon as Katherine Catherine, and Lorne Michaels as Reverend Gimp. Conan O'Brien, a former Saturday Night Live (1975) writer from 1987-1991, also appeared as himself in two episodes, and was the inspiration for season four, episode eighteen, "Khonani".

Rachel Dratch's appearance as various characters throughout the show is a fourth-wall-breaking display of improvisation, a topic in many of the episodes.

The title is derived from 30 Rockefeller Plaza, the New York City street address of NBC Universal.

Jason Sudeikis and James Marsden share the same birthday (September 18) and played love interests of Liz Lemon.

A different actress portrayed Cerie in the unaired pilot. Katrina Bowden was only seventeen-years-old at the time she was re-cast as Liz's careless young assistant. When Bowden arrived for the table read for the second version of the pilot, she did not know what Alec Baldwin and Tracy Morgan looked like, as she had only heard their names. Bowden turned eighteen a month before this show first aired.

Hazel Wassernam's real name is Richard Drench, a play on Rachel Dratch.

The art on the wall behind Liz Lemon's desk (that features two round objects next to each other) is actually two thermostat dials, surrounded by colored posterboard and a frame.

This show aired two live episodes, season five, episode four, "Live Show", and season six, episode nineteen, "Live from Studio 6H", but first did a live show during the Writers Guild of America strike of 2007-2008 to raise money for the writers. The actors performed an episode that had already aired in front of a live audience and had so much fun, they decided to do a live show for broadcast.

The character Frank Rossitano (Judah Friedlander) is named after Saturday Night Live (1975) stage manager Gena Rositano.

In Season one, Rachel Dratch appears in every episode as a different character.

Elizabeth Banks played a character on Scrubs (2001) who was impregnated by a character named J.D. (John Dorian). On this show, she was impregnated by another character with initials J.D. (Jack Donaghy).

Liz's boyfriend Criss Chros was named after singer Christopher Cross, who was a fan of the show. In season four episode sixteen, "Floyd", a tearful Liz sings a song about her ex-boyfriend that she envisions Cross singing as a soundtrack to their relationship. Cross was flattered, and actually finished the song, sending a recording to the show. To thank him, they named Criss after him.

The show's name is similar to "3rd Rock", the commonly used short title for 3rd Rock from the Sun (1996). At The 64th Annual Golden Globe Awards (2007), Tim Allen mispronounced the show's name as "3rd Rock" when mentioning that Alec Baldwin had been nominated for the Best Actor in a Television Comedy or Musical Award. Both shows featured guest appearances by Elaine Stritch as the mother of one of the main characters.

Tina Fey and Scott Adsit did voice work for the pinball game Medieval Madness.

Tina Fey (Liz Lemon), Jack McBrayer (Kenneth Parcell), and Scott Adsit (Pete Hornberger) have all provided their voices for work in Disney films. Fey in Monkey Kingdom (2015), McBrayer starred as Fix It Felix in Wreck-It Ralph (2012), and Adsit as Baymax in Big Hero 6 (2014).

Will Forte, Mary Steenburgen, and Kristen Schaal guest starred on this show before appearing in The Last Man on Earth (2015).

This show included several references to "Star Wars" character Lando Calrissian, played by Billy Dee Williams in Star Wars: Episode V - The Empire Strikes Back (1980) and Star Wars: Episode VI - Return of the Jedi (1983). Donald Glover, who got his big break when he was hired as a writer for this show in 2006, portrayed a young Lando Calrissian in Solo: A Star Wars Story (2018).

Alec Baldwin (Jack) and Michael Keaton (Tom) starred in Beetlejuice (1988).

Over the course of the series, there were many hints that Kenneth was considerably older than the character's outward appearance would suggest (the actor who plays Kenneth, Jack McBrayer, was in his early thirties when this show started). These include Kenneth's recognition of television pop culture from decades before he logically would have been born, his knowledge of the laws of the Roman Republic and fluency in Latin, his anxiety in season four, episode fifteen, "Don Geiss, America and Hope",that NBC would start limiting and verifying the ages of their pages, and his concern in season four, episode five, "Problem Solvers", that people in the office have been spreading a rumor that he's "been alive forever". He states that an eight-year-old Shirley Temple taught him how to roll cigarettes, refused to tell Suze Orman his age in season six, episode five, "Today You Are a Man", and he was identified as "Kenneth Parcell: Elderly Page" in season five, episode seventeen, "Queen of Jordan". In season seven, episode two, "Governor Dunston", Kenneth's mother (Catherine O'Hara) visits and tells Jenna that Kenneth has "always been a special boy. I remember the day he was born. He looked up at me and said, 'Momma, I am not a person. My body's just a flesh vessel for an immortal being whose name if you heard it would make you lose your mind.'" In the series finale, Kenneth looks to be exactly the same even many decades in the future, still the President of NBC, hearing a series pitch from Liz's great-granddaughter.

Kenneth said in an episode that when he first started at NBC, an eight-year-old Shirley Temple taught him how to roll a cigarette. Temple was born in 1928, which means Kenneth started at NBC in 1936.

A running gag in season one was the inability to understand or pronounce the name of Jenna's low-budget film "The Rural Juror", based on a novel by Kevin Grisham. It was often just pronounced as "Rrurr Jjurr". In the series finale, Jenna sings the theme song of the musical "The Rural Juror". The song has utterly incomprehensible lyrics for the public. However, it is the first time Jenna pronounces "The Rural Juror" correctly. One of the lyrics that was pronounced perfectly was "I will never forget you, rural juror."
