The origins of tomato soup are lost in the jungles of South and Central America. At "some" point in time, "someone" threw tomatoes into a pot, cooked them for a while with water, removed the skins and drank/ate the contents.

So tomato soup spread across the world as did its principal ingredient. Tomato soup was the first soup introduced by Campbell's in 1897.

Today, tomato soup is most widely sold in the canned condensed form, though powdered forms are available for campers. Campbell's Soup has sold over 20 billion cans in the U.S. - Tomato soup is one of the top ten grocery items purchased weekly in America.

Trivia: The citizens of Minneapolis consume more canned condensed tomato soup per person per year than almost anywhere else in the country.

I'd encourage you to raise your own tomatoes and make your own soup, but I'm in touch with contemporary society enough to know that LOL would be the typical response. However, health conscious Americans have begun to read labels on cans, and the recent declines in domestic consumption of canned soups have forced manufacturers to revise their recipes. MSG was first ingredient to be taken out (caused migraine headaches), but the flavor suffered and consumers complained, thus the amount of salt was increased. As the adverse effect of high sodium consumption became clear, manufacturers began to experiment to find ways to keep flavor while reducing salt. Campbell's found that they had to use sea salt because it has more flavor than rock salt.
