How many hot dogs do Americans consume over July 4th holiday?

According to the National Sausage and Hot Dog Council (NHDSC), Americans are expected to eat 150 million hot dogs over the July 4th holiday alone, part of the 7 billion hot dogs eaten over the summer season from Memorial Day to Labor Day.

How did the modern day hot dog become such an iconic part of America? It’s a tough question to answer and even the NHDSC offers little clarity:

“It is likely that the North American hot dog comes from a widespread common European sausage brought here by butchers of several nationalities. Also in doubt is who first served the dachshund sausage with a roll. One report says a German immigrant sold them, along with milk rolls and sauerkraut, from a push cart in New York City’s Bowery during the 1860′s. In 1871, Charles Feltman, a German butcher opened up the first Coney Island hot dog stand selling 3,684 dachshund sausages in a milk roll during his first year in business.”
