New Delhi, July 16 -- Americans will devour over 7 billion hot dogs this summer, about 818 every second, with today (July 16) marking the peak celebration! Known as "hot dog season," the period between Memorial Day and Labor Day accounts for 38% of annual sales ($1.16 billion).

This tradition dates back to German immigrants in the 1860s, who first sold sausages in New York streets.

The National Hot Dog and Sausage Council established today's festivities to honor this iconic food, with regional twists like Chicago's no-ketchup rule and Seattle's cream cheese-topped dogs drawing nationwide enthusiasm.
