Marketing changes over time

In the early 19th Century agriculture began to change so fast and so many new products and technologies were being introduced that farmers need one place to see them all.  That was the origin of the Exposition.

Over that century expos expanded to include a wide range of technologies including architecture and home products.  By the end of the 19th Century we had national expos that displayed the technology of entire nations and we had religious expos that introduced new religions.  Buddhism, Hinduism and Bahai came to America with the great religious expo of 1893. 

By the end of the 19th Century the word fair and expo became interchangeable.

Big change in marketing from a large array to select from to a new mode. Have you noticed that by the 1960's the fairs and expos were becoming quite irrelevant and boring.  Merely show cases for the newly emerging national technology competition.

My key insight is that today, fairs and expos, have gone from technology marketing demonstrations to national technology competitions and have now migrated to Olympics.  Olympics are the new national marketing scene where national ideologies and social values are on display.
