GLOW is an American comedy-drama television series created by Liz Flahive and Carly Mensch for Netflix. The series revolves around a fictionalization of the characters and gimmicks of the 1980s syndicated women's professional wrestling circuit Gorgeous Ladies of Wrestling (or GLOW) founded by David McLane.
 The first season consists of 10 episodes and was released on June 23, 2017. On August 10, 2017, Netflix renewed the series for a second season of 10 episodes, which was released on June 29, 2018. The series was renewed on August 20, 2018, for a third season, which was released on August 9, 2019. On September 20, 2019, the series was renewed for a fourth and final season. However, in October 2020, that decision was reversed by Netflix, and the final season was canceled due to the COVID-19 pandemic causing a production shutdown.
 In Los Angeles in 1985, Ruth Wilder, a struggling actress, auditions along with many other women in a fledgling professional wrestling promotion called the Gorgeous Ladies of Wrestling (GLOW). Traditionally minded in her approach to acting and highly idealistic, she clashes with GLOW's director Sam Sylvia due to his cynical demeanor and often unconventional work style. Ruth discovers early on that Sylvia has employed her former best friend, retired soap opera actress Debbie Eagan to star in the show. Ruth and Debbie had fallen out with one another after Ruth had an affair with Debbie's husband, Mark, whom Debbie then divorced. The tension between the two women promises either to make or break the developing show. The series follows the personal and professional lives of the fictional show's numerous cast and crew as they navigate the 1980s in Southern California and Southern Nevada.
  
 The show's cast features several real-life professional wrestlers, most prominently Kia Stevens (Tammé), who has wrestled as Awesome Kong for TNA and AEW while wrestling as Kharma for WWE. Others with formal experience include:
 Hulk Hogan, Ric Flair, and Gorgeous George appear in archived video footage in episodes 1 and 4.
 The idea for the series came when Flahive and Mensch, who at the time were looking to make a new female-centric show, came across the 2012 documentary GLOW: The Story of the Gorgeous Ladies of Wrestling. Before this, neither woman had heard of the GLOW wrestling promotion, and they became intrigued by the premise of producing a fictionalized version of it. They found the storyline intriguing as a way of exploring the aftermath of the 1970s Woman's Liberation Movement, with Flahive telling Rolling Stone, "We wanted to look back on the 1970s, coming out of the women's movement, and into the 1980s, and ask the question: Did it work? Did things get better?" To this end, it was important for the series to maintain a tension between whether the league was exploiting women or empowering them.
 Ursula Hayden, the owner of the GLOW company, served as a consultant on the series and helped Flahive and Mensch with creating the show. Hayden was also on the original 1980s promotion as Babe, the Farmer's Daughter.
 Chavo Guerrero Jr. of the famous Guerrero wrestling family also served as a consultant on the series and helped train the actresses. His uncle, Mando Guerrero, had served in the same role for the original series. Guerrero Jr. also appeared in two episodes of the second season, including the season finale.
 The series filmed in several locations in Los Angeles; mainly in the San Fernando Valley. Chavo's Boxing Gym, which is GLOW's training grounds, was a combination of two locations: the interior was a studio set while the exterior was the rear of the San Fernando Masonic Lodge. The Pink Motel in Sun Valley was used as a stand-in for The Dusty Spur Motel, GLOW's sleeping quarters. Other locations included the Mayan Theater and the Hollywood Palladium.
 Principal production on the second season began in October 2017.
 For the Spain market, Netflix España released a series of promo videos featuring singers Marta Sánchez and Vicky Larraz. The first video, titled "No Controles", features Sánchez imitating Ruth's imaginary wrestler scene from the first episode. The second video has Sánchez and Larraz squaring off in the ring.
 For the Brazil market, Netflix Brasil released a promo video featuring singers Gretchen and Rita Cadillac auditioning for GLOW.
 Funko released Pop! Vinyl figures of Ruth and Debbie in mid-2018.
 In September 2019, Netflix renewed the show for a fourth and final season. On February 19, 2020, Alison Brie posted a photo from the set on Instagram, signaling that they were beginning production on the final episodes. In March 2020, production on the season was shut down due to the COVID-19 pandemic, which had stopped nearly all TV and film productions in Los Angeles. They had already completed the first episode and were about to start filming the second.
 On October 5, 2020, creators Liz Flahive and Carly Mensch announced that the fourth season was canceled and would not be completed or aired. It was explained that the show had some of the biggest obstacles to overcome as Netflix was trying to figure out how to get their shows back to work, mostly due to uncertainty about how to prevent an outbreak on set with its wrestling theme and increased COVID-19–related costs added to an already expensive budget. The earliest the show's final season would have aired was in 2022, which would have been too long of a gap for Netflix to handle, as the previous season aired in 2019.
 The series features several songs from the 1980s, as well as tracks from the 1950s, 1960s, and 1970s. The opening theme used for the full-length opening titles in episode 1 of each season is "The Warrior" by Scandal.
 Quiet Riot's cover of "Cum On Feel the Noize" was used for the Season 1 trailer, while "Maniac" by Michael Sembello was used for the Season 2 trailer and "Listen to Your Heart" by Roxette for the Season 3 trailer. Songs covered by the cast include the Thompson Twins' "Hold Me Now" and Barbra Streisand's "This Is One of Those Moments".
 GLOW was praised by critics upon its release. On Rotten Tomatoes, season 1 has a 94% approval rating with an average score of 7.66/10 based on 107 reviews. The site's critical consensus reads, "With spot-on 1980s period detail, knockout writing, and a killer cast, GLOW shines brightly." The first season has a Metacritic score of 81 out of 100, based on 37 critics, indicating "universal acclaim". Darren Franich of Entertainment Weekly gave the first season an A rating, calling it "a silly-smart masterpiece, with an ensemble cast entirely made up of breakout characters". Sophie Gilbert of The Atlantic said, "...it’s just a blast to watch women having so much fun. GLOW fully owns its campiness and its showy aesthetics, but it’s smart and subversive underneath the glitter."
 The second season received even higher critical acclaim. On Rotten Tomatoes, season 2 has a 98% approval rating with an average score of 8.77/10 based on 84 reviews. The site's critical consensus reads, "Fearlessly led by its excellent ensemble, GLOW's second season adds a new layer of drama without sacrificing its self-effacing, delightfully silly humor." The second season has a Metacritic score of 85 out of 100, based on 20 critics, indicating "universal acclaim".
 On Rotten Tomatoes, the third season has an 86% approval rating with an average score of 8/10 based on 65 reviews. The site's critical consensus reads, "GLOW dives even deeper into the lives of its divas to deliver a knock-out third season that solidifies its place as one of TV's most compelling—and hilarious—character studies." The third season has a Metacritic score of 80 out of 100, based on 17 critics, indicating "generally favorable reviews".
 The series received mixed reactions from some of the original GLOW wrestlers. Jeanne Basone, who wrestled in the promotion as "Hollywood", commented that "Some of the training and the gym and the outfits they get correct." Patricia Summerland, who played "Sunny the California Girl" in the promotion, saw Marc Maron's character Sam Sylvia as a stark contrast to original GLOW director Matt Cimber. Eileen O'Hara, who was known as "Melody Trouble Vixen (MTV)", felt that the series did not properly acknowledge how groundbreaking they were. Lisa Moretti, who competed as "Tina Ferrari" and would go on to the greatest fame among GLOW alumnae as Ivory in the WWF/WWE as a three-time WWF Women's Champion during the Attitude Era, said that she was relieved that the series isn't a documentary because it was more entertaining to have a mix between fact and fiction.
 More positive reception came from mainstream wrestling figures including Kurt Angle. Ethan Sapienza of Slate noted accurate comparisons between the series and WWE as well as the various regional promotions that made up the National Wrestling Alliance during its heyday.
 A four-issue comic book series based on the show was released in March 2019 by IDW Publishing, written by Tini Howard and illustrated by Hannah Templer.
