[2] The Big E is inclusive of all six New England states: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.

[4] The Boys & Girls Clubs of America partnered with the Exposition to organize youth competitions, in which prizes were awarded for best produce, jams, breads, raised hens, planting techniques, and other categories.

Emphasis on the development of young farmers continued with the establishment of "Baby Beef Clubs" in 1920 to help youths buy, raise, exhibit, and sell livestock at the event.

In 1923, the Massachusetts Department of Health built a model schoolhouse on the fairgrounds, offering free medical and dental examinations.

At that year's horse show in West Springfield, competitors from Delaware, New Jersey, and New York were placed in the open classes instead of the New England division.

[13] In 1966, for its fiftieth anniversary, the fair began marketing itself as "The Big E." The "E" stands for what organizers said was an emphasis on "entertainment, education and excitement.

[16] The Maine baked potatoes have become an icon, with buyers regularly joining long lines during the fair's busier periods.

The Big E remains true to its agricultural roots today, with more than 7,100 4-H and FFA participants, and 1,100 open-show exhibitors, as well as educational displays and attractions.

Small shops are a primary attraction of the Big E. Vendors can be found across most of the fairgrounds, selling items ranging from state-specific trinkets and regional memorabilia to household goods, clothing, and accessories.

The Better Living Center is the largest vendor area, featuring household wares, home improvement services, cookware, and health supplements.

The International Building is home to vendors selling items from other cultures, in particular those with a common connection with many New Englanders, in particular Irish and Italian imported goods.
