Krispy Kreme is celebrating their 75th birthday with a bang. From 7 to 10 p.m. tonight, the company will host a street party on Trade Street in Winston-Salem, N.C., with free hot original glazed doughnuts and live music. Tomorrow, a Family FanFest from 9 a.m. to noon in Old Salem will offer more free doughnuts, coffee, rides and games.

Krispy Kreme doughnuts were founded on July 13, 1937 in Winston-Salem, N.C., by Vernon Rudolph. The original recipe, bought from a New Orleans chef, was sold in a local grocery store. Rudolph began selling them from a window to passersby on the street. In the 1950's, the company opened their first plant and has expanded ever since.

In honor of their birthday, the company has released a birthday doughnut with frosting and sprinkles. A special promotion going on today offers a dozen original glazed doughnuts for 75 cents with the purchase of a dozen doughnuts.
