Riverdale Doesn’t Exist in a Specifically Defined Time Period Cole Sprouse confirmed that Riverdale doesn't take place in an exact time period after fans expressed their confusion of the show having both a 1950s vibe and modern technology. "Riverdale has no formal or announced time period as of now," he wrote during a Reddit AMA. "And with the amount of money we dedicate to atmospheric fog, the setting is supposed to feel dream-like."
