Factual error: There is an episode where Reagan is running for president in 1984, and later in this episode they are watching "America's funniest home videos" which started in 1989.
Factual error: Occasionally one of the characters will make a key reference to some film or other cultural event that took place in 1989 or later. Like the neighbor stating she saw Ghost, which came out in 1990.
Factual error: The Phillies were in the World series in 1980. Talk into remote controls did not come out till 1989. The party in the park the kids are dancing to the song "Tricky" by Run DMC which came out in 1986.
Suggested correction: The Phillies were in the 1983 World Series as well (which is the likely year as they lost), and the Goldbergs didn't have a talk in remote - the kids said they had just to wind up their father.
