In 1974, authorMichael Crichton wrote a screenplay then titled "EW" (forEmergency Ward) based on his own experiences as amedical student in a busy hospitalemergency room.[4] Producers were not interested in the screenplay, and Crichton turned to other topics. In 1990, he published the novelJurassic Park, and in 1993 began a collaboration with directorSteven Spielberg on thefilm adaptation of the book.[5]
After its release, Crichton and Spielberg then turned to what was now known asER, but Spielberg decided to film the story as a two-hour pilot for a television series rather than as a feature film after considering the potential for various stories to be told in the setting.[6] He passed the script on to a team at his production company,Amblin Entertainment.Anthony Thomopoulos, then head of Amblin's television division, got in touch with then CEO ofWarner Bros. Television,Les Moonves, about the idea for the series and to send the script. Spielberg'sAmblin Television providedJohn Wells as the show's executive producer.
Warner Bros. Television pitchedER toNBC, alongside Crichton, Spielberg and Wells.Warren Littlefield, head ofNBC Entertainment at the time, liked the project, but there was much debate and controversy among other executives at NBC, who were dubious about the nature of the series. NBC offered a chance to make a two-hourmade-for-TV movie from the script, which was rejected. They then tried to get the show greenlit at rival networks before returning to NBC, who this time around ordered apilot.
The script used to shoot the pilot was virtually unchanged from what Crichton had written in 1974. The only substantive changes made by the producers in 1994 were that a male character was changed to a female character (Susan Lewis) and thePeter Benton character's race was changed to African-American. The running time was shortened by about 20 minutes in order for the pilot to air in a two-hour block on network TV.[citation needed] Because of a lack of time and money necessary to build a set, the pilot episode ofER was filmed in the formerLinda Vista Hospital inLos Angeles, an old facility that had ceased operating in 1990.[7][8] A set modeled afterLos Angeles County General Hospital's emergency room was built soon afterward at theWarner Bros. Studios inBurbank, California, although the show makes extensive use of location shoots inChicago, most notably the city's famous"L" train platforms.[9]
Littlefield was impressed by the series: "We were intrigued, but we were admittedly a bit spooked in attempting to go back into that territory a few years afterSt. Elsewhere."[10] With Spielberg attached behind the scenes, NBC ordered six episodes. "ER premiered opposite aMonday Night Football game onABC and did surprisingly well. Then we moved it to Thursday and it just took off," commented Littlefield.[10]ER's success surprised the networks and critics alike, asDavid E. Kelley's new medical dramaChicago Hope was expected to crush the new series, airing directly oppositeER in the Thursday 10:00 pm time slot over onCBS.[11]
Crichton was credited as an executive producer until his death in November 2008, although he was still credited as one throughout that entire final season. Wells, the series' other initial executive producer, served asshowrunner for the first four seasons. He was the show's most prolific writer and became a regular director in later years.Lydia Woodward was a part of the first season production team and became an executive producer for the third season. She took over as showrunner for the fifth season while Wells focused on the development of other series, includingTrinity,Third Watch, andThe West Wing. John Wells continued to serve as the primary Executive Producer for the remainder of the series.[12] Lydia Woodward left her executive producer position at the end of the sixth season but continued to write episodes throughout the series run.
Joe Sachs, who was a writer and producer of the series, believed keeping a commitment to medical accuracy was extremely important: "We'd bend the rules but never break them. A medication that would take 10 minutes to work might take 30 seconds instead. We compressed time. A 12- to 24-hour shift gets pushed into 48 minutes. But we learned that being accurate was important for more reasons than just making real and responsible drama."[10]
Woodward was replaced as showrunner byJack Orman. Orman was recruited as a writer-producer for the series in its fourth season after a successful stint working on CBS'sJAG. He was quickly promoted and became an executive producer and showrunner for the series' seventh season. He held these roles for three seasons before leaving the series at the end of the ninth season. Orman was also a frequent writer and directed three episodes of the show.
David Zabel served as the series' head writer and executive producer in its later seasons. He initially joined the crew for the eighth season and became an executive producer and showrunner for the twelfth season onward. Zabel was the series' most frequent writer, contributing to 41 episodes. He also made his directing debut on the series.Christopher Chulack was the series' most frequent director and worked as a producer on all 15 seasons. He became an executive producer in the fourth season but occasionally scaled back his involvement in later years to focus on other projects.
Following the broadcast of its two-hourpilot on September 19, 1994,ER premiered Thursday, September 22 at 10pm. It remained in the same Thursday time slot for its entire run, capping theMust See TV primetime block.[13]ER is NBC's third longest-running drama, afterLaw & Order: Special Victims Unit andLaw & Order,[14] and the second longest-running American primetime medical drama of all time, behind ABC'sGrey's Anatomy.[15] Starting with season seven,ER was broadcast in the1080i HD format, appearing inletterbox format when presented in standard definition.[16] On April 2, 2008, NBC announced that the series would return for its fifteenth season.[17] The fifteenth season was originally scheduled to run for 19 episodes before retiring with a two-hour series finale to be broadcast on March 12, 2009,[18][19] but NBC announced in January 2009 that it would extend the show by an additional three episodes to a full 22-episode order as part of a deal to launch a new series by John Wells titledPolice, later retitledSouthland.[20]ER'sfinal episode aired on April 2, 2009; the two-hour episode was preceded by a one-hour retrospective special.[21] The series finale charged $425,000 per 30-second ad spot, more than three times the season's rate of $135,000.[10] From season 4 to season 6ER cost a record-breaking $13 million per episode.[22]TNT also paid a record price of $1 million an episode for four years of repeats of the series during that time.[23] The cost of the first three seasons was $2 million per episode and seasons 7 to 9 cost $8 million per episode.[22][24]
In addition to the main cast,ER featured a large number of frequently seen recurring cast members who played key roles such as paramedics, hospital support staff, nurses, and doctors.ER also featured a sizable roster of well-known guest stars, some making rare television appearances, who typically played patients in single episode appearances or multi-episode arcs.
A typical episode centered on the ER, with most scenes set in the hospital or surrounding streets. In addition, most seasons included at least one storyline located completely outside of the ER, often outside ofChicago. Over the span of the series, stories took place in theCongo,Iraq,France, andSudan. One early storyline involved a road trip taken by Dr. Ross and Dr. Greene toCalifornia and a season eight episode included a storyline inHawaii featuring Dr. Greene and Dr. Corday. Beginning in season nine, storylines started to include the Congo, featuring Dr. Kovač, Dr. Carter, and Dr. Pratt.[43] "We turned some attention on the Congo and onDarfur when nobody else was. We had a bigger audience than a nightly newscast will ever see, making 25 to 30 million people aware of what was going on in Africa,"ER producerJohn Wells said. "The show is not about telling people to eat their vegetables, but if we can do that in an entertaining context, then there's nothing better." The series also focused on sociopolitical issues such asHIV andAIDS,organ transplants,mental illness,racism,human trafficking,euthanasia,poverty andgay rights.[44]
Some episodes used creative formats, such as the 1997 "Ambush," which was broadcast live twice, once for the east coast and again three hours later for the west coast,[10] and 2002's "Hindsight," which ran in reverse time as it followed one character, Dr. Kovač, through the events of a Christmas Eve shift and the Christmas party that preceded it.
The episode "Brothers and Sisters" (first broadcast on April 25, 2002) begins a crossover that concludes on theThird Watch episode "Unleashed" in which Dr. Lewis enlists the help of Officers Maurice Boscorelli and Faith Yokas to find her sister and niece.

For almost five years,ER battled for the top spot againstSeinfeld, but in 1998,Seinfeld ended and thenER became number one again. Theseries finale attracted 16.4 million viewers.[60] The show's highest rating came during the episode "Hell and High Water" with 48 million viewers and a 45% market share. It was the highest for a regularly scheduled drama since a May 1985 installment ofDallas received a 46. The share represents the percentage of TVs in use tuned in to that show.[61]
Throughout the seriesER received positive reviews from critics and fans alike.Marvin Kitman fromNewsday said: "It's likeM*A*S*H with just the helicopters showing up and no laughs.E.R. is all trauma; you never get to know enough about the patients or get involved with them. It's just treat, release and move on."[62]Richard Zoglin fromTIME stated that it's "probably the most realistic fictional treatment of the medical profession TV has ever presented."[63]
NBC launched the show at the same time thatCBS launched its own medical dramaChicago Hope; many critics drew comparisons between the two. Eric Mink, writing for theNew York Daily News, concluded thatER may rate more highly in theNielsens butChicago Hope told better stories,[64] whileAlan Rich, writing forVariety, felt both shows were "riveting, superior TV fare."[65]The Daily Telegraph wrote in 1996: "Not being able to follow what on earth is going on remains one of the peculiar charms of the breakneck American hospital drama,ER."[66]
In 2002,TV Guide rankedER No. 22 on their list of "TV's Top 50 Shows," making it the second highest ranked medical drama on the list (afterSt. Elsewhere at No. 20).[67] Also, the episode "Love's Labor Lost" was ranked No. 6 onTV Guide's 100 Greatest Episodes of All-Time list having earlier been ranked No. 3.[68] The show placed No. 19 onEntertainment Weekly's "New TV Classics" list.[69]Empire ranked it No. 29 in their list of the "50 Greatest TV Shows of All Time" and said the best episode was "Hell and High Water" where "Doug Ross (George Clooney) saves a young boy from drowning during a flood."[70] In 2012,ER was voted Best TV Drama onABC's20/20 special episode "Best in TV: The Greatest TV Shows of Our Time."[71] In 2013,TV Guide ranked it No. 9 in its list of The 60 Greatest Dramas of All Time[72] and No. 29 in its list of the 60 Best Series.[73] In the same year, theWriters Guild of America rankedER No. 28 in its list of the 101 Best Written TV Series of All Time.[74]

The DVD box sets ofER are unusual in the fact that they are all inanamorphic widescreen even though the first six seasons of the show were broadcast in a standard 4:3 format.ER was shotprotecting for widescreen presentation, allowing the show to be presented in 16:9open matte (leaving only the title sequence in the 4:3 format). However, as the production of the show was generally conceived with 4:3 presentation in mind, some episodes feature vignetting or unintended objects towards the sides of the frame that would not be visible when presented in the 4:3 format. These episodes also appear in the widescreen format when rerun onTNT HD,Pop and streaming services.
In 1996,Atlantic Records released an album of music from the first two seasons, featuringJames Newton Howard's theme from the series in its on-air and full versions, selections from the weekly scores composed by Martin Davich (Howard scored the two-hour pilot, Davich scored all the subsequent episodes and wrote a new theme used from 2006–2009 until the final episode, when Howard's original theme returned) and songs used on the series.[81]

Original cast memberNoah Wyle revealed that in 2020 there were talks to revive the show. However, development of that series stalled due to issues with the estate of creatorMichael Crichton, and in early 2024, Wyle was announced as starring in a new medical drama fromWarner Bros. and originalER showrunnerJohn Wells,The Pitt.[88] That August, the Crichton estate brought a lawsuit against Warner Bros., Wells, and Wyle, alleging thatThe Pitt was in fact an unauthorized remake ofER which could not be produced without the estate's approval; Warner Bros. has denied the allegation, callingThe Pitt "a new and original show."[89]
