In many ways Now and Then is a veritable time capsule, not just of 1970, but also of the year the film was released, 1995, which is a major thing adults notice in the movie that youngsters might not. Archaic objects like battery-powered transistor radios, rotary phones, non-electric vacuum cleaners, and even non-digitized library newspaper archives bound in leather were all in common use back in the 1970s before technology began its leaps forward. 

Only adults would also notice the now-defunct Yardley Cosmetics on Chrissy's vanity, how a print version of TV Guide is only 99 cents and Sam's hardcover book is $15.99, and that Sam uses a paper map to navigate. That's not even mentioning the answering machines and the VCR in Teeny's limousine. All relics now.

But what's almost more striking is how much has changed behavior-wise since 1995. Chrissy douses her hair with Aquanet hairspray even though she's about to have her baby at any moment, something adults know today could be toxic to the unborn child. Worse, Sam is a chainsmoker, and she and Teeny smoke around pregnant Chrissy without anyone mentioning it. To kids, this may look bizarre, but, to adults today, we know just how risky those behaviors were, though, if you lived through those times, it was considered normal.
