“I was quite shocked when I realized the show was set in the 1970s, only realizing it after I saw the appliances on set”Debra Jo Rupp said in speaking with Entertainment Weekly. As far as he recalls, this detail was not specified anywhere in the script, and at the beginning That ’70s Show was called The Kids Are Alright (like the Who song).
