I love going to the farmer's market. I haven't in a long time, but I used to buy raw milk there straight from the farmer.
Why is it called farmers market.Does it mean its exclusive to farmers only?
It is called a farmer's market because consumers can buy products directly from the farmers in a physical retail marketplace.
OK, ,when was the earliest history of such markets?
Forms of marketplaces like this existed before the Industrial age, but were often part of a much broader market where suppliers also bought their goods.
That good.Is it regulated by the government or is it a free and open market operations?
I'm not 100% sure of the details, but due to their nature they do tend to be less rigidly regulated than your typical retail shop for produce.
