The name Groupon is a combination of the words group and coupon, which references the company's viral marketing business model.
The name Groupon is a blend of âgroupâ and âcouponâ. Groupon's first deal was a half-price offer for pizzas at Motel Bar, a restaurant on the first floor of its building in Chicago.
