In 1999, the show was remade for the ITV network in the United Kingdom as Days Like These using almost verbatim scripts with minor changes to cultural references.
The remaining episodes took place in 1979, and the series finale abruptly ends during a New Year's Eve party as the characters reach "one" during a countdown to January 1, 1980.
Eric Forman was written out of the series at the end of the seventh season, as Topher Grace wanted to move on with his career.
[6] However, Kelso had not been written out yet, so to give better closure to the character, Kutcher appeared in the first four episodes of the eighth season (credited as a special guest star).
Tommy Chong (who began reappearing by late season 7 after a long absence) became a regular again to help fill Kelso's role as the dimwit of the group.
[11] The show addressed many social issues of the 1970s such as sexual attitudes of the era, generational conflict, the economic hardships of the 1970s recession, mistrust of the American government by blue-collar workers, and underage drinking/drug use.
The series also highlighted developments in fashion trends,[12] the entertainment industry, including the television remote ("the clicker"), reruns, VCRs, and cable TV; the video games Pong and Space Invaders; the cassette tape and Disco; MAD magazine; and Eric's obsession with Star Wars, which came out in 1977.
In the episode "Bye-Bye Basement", Theo (Leo's cousin) refers to "weed"; in "The Relapse", Kelso tells Fez that the concrete wall behind the gym is used mostly for "smoking weed and beating up freshmen;" in "Ski Trip" Kitty asks Eric why he is taking so much oregano to Jackie's ski lodge; in "Eric's Burger Job", Kelso blames his "roach clip" when the water bed on which he is sitting at a party deflates; in two episodes ("That Wrestling Show" and "Hyde Moves In"), Eric and Hyde can be seen wearing shirts with the words "Cannabis sativa" written on a Campbell's soup can; and in "The Pill", Red, referring to Kelso, exclaims, "That kid's on dope!"
During the eighth and final season, The Circle (sans the smoke) replaced the Formans' Vista Cruiser as the setting of the opening credits.
On November 3, 2015, Mill Creek Entertainment released That '70s Show The Complete Series on Blu-ray 1080p, featuring all 200 episodes from the series, presented digitally remastered in High Definition from the original film negatives for optimum sound and video quality and for superior home entertainment Blu-ray presentation with remastered 5.1 DTS-HD Master Audio surround sound and 16:9 widescreen aspect ratio.
[29][30] Netflix produced a spin-off of the series, titled That '90s Show, with Kurtwood Smith and Debra Jo Rupp reprising their roles as Red and Kitty Forman, respectively.
[31] Topher Grace (Eric Forman), Mila Kunis (Jackie Burkhart), Ashton Kutcher (Michael Kelso), Laura Prepon (Donna Pinciotti), Wilmer Valderrama (Fez), Tommy Chong (Leo), Don Stark (Bob Pinciotti), Jim Rash (Fenton) and Seth Green (Mitch Miller), reprised their roles as guest stars in the series.
