"That '70s Show" ran on Fox from 1998 to 2006 and starred Topher Grace as Eric Foreman, a teenager living in the 1970s in Wisconsin who spends time with his friends Hyde (Danny Masterson), Kelso (Ashton Kutcher), his neighbor Donna (Laura Prepon), and Kelso's girlfriend Jackie (Mila Kunis). The show's timeline ended with New Year's Eve in 1979.
The program featured guest turns by many actors who had been famous on 1970s TV shows, including Mary Tyler Moore of the show of the same name, Tom Bosley and Marion Ross of "Happy Days," and "The Brady Bunch" cast members Barry Williams, Christopher Knight, and Eve Plumb.
While early seasons of the show included frequent use of dream sequences and often had plot lines revolving around the characters' high school, later seasons dropped the imagined segments and mostly didn't show the characters during school hours.
