Movies
1915: Black and white, and silent
1965 and 2015: not so diferente

Clothes
1915: Men wear suits, women wear long dresses every day
1965 and 2015: Men wear suits only in the workplace (if they work at an office). Women wear suit or blouse and skirt or dress in the workplace. In the free time, men wear T-shirt, shorts or paints. Women wear blouse, short skirt, knee-lengh skirt or long skirt, short dress or long dress, or paints, or shorts. Men and women wear jeans.
Until 1920, women used to wear only long skirts. Between 1920 and 1960, the skirt lengths went up and down, up and down... but in each year, it was standardized. From 1960 to the present day, women can wear paints but also every skirt length.
Until 1960, men used to wear suits even in the weekend. Since this date, men wear athlete's clothes even when they are not practicing sports.

Music
1915: rock did not exist
1965 and 2015: rock exists

Aircraft
1915: used for war. Only one seat. Short range.
1965: Boeing 707
2015: Boeing 777. Not too many diferences if compared to the 707

Example of a famous car
1915: Ford T. Few households owned a car
1965: Mustang
2015: Focus 3rd generation

Cellphones, digital cameras and personal computers are few examples that make the distance between 1965 and 2015 bigger than the distance between 1915 and 1965. OK, I am typing this text using a personal computer, but it is not hard to say that Technologies from the 3rd industrial revolution did not affect the daily life so much as the technologies from the 2nd industrial revolution. Many technologies from the 2nd industrial revolution already existed in 1915, but they were not so spread.

For the whole population from the developed countries and for the middle/upper class from the developing countries, life changed much more between 1915 and 1965 than between 1965 and 2015. But for the poor people from the developing countries, life might have changed more between 1965 and 2015. Many of them owned a cell phone for the first time in their lives before owning a car.

1915 in eastern France?
1965 in southeastern Asia?
2015 in Syria?


Now, talking serious, in 1915 I wouldn't like to live even in the USA

A citizen from 1965 who traveled to 2015 would have asked "where are the flying cars"?

An important change which took place between 1965 and 2015 was the decline of the mass audience, which happened because of the Video Cassette Recorder, the cable TV, the Internet, the DVD set, Youtube, Netflix. There was  segmentation of the audience.
However, this is not more important than the rise of the mass audience which took place between 1915 and 1965.
