Is it just me for is Bachelor Father really more a 1960's sitcom? The cars, the clothes, the hairstyles, etc., are much more 1960's than 1950's IMO.

It ran from 1957-1962 I believe, so its a little of both eras I guess.

Roadster I think you may be right! Sitcoms Online convention is to categorize a show within the decade that the majority of its run took place. BF's run was 2 years, 3 months within the 50s, 2 years 9 months within the 60s.

However, three of its seasons started in the 50s. Only two seasons started in the 60s.
