The chain operates 29 locations. It is notable for its title of "America's First Supermarket" as recognized by the Smithsonian Institution. King Kullen meets the criteria of America's First Supermarket because it was “the first to fulfill all five criteria that define the modern supermarket: separate departments; self-service; discount pricing; chain marketing; and volume dealing.”  The Food Marketing Institute has stated that King Kullen “served as the catalyst for a new age in food retailing. The Super Market Institute recognizes that there is dispute regarding which store is America’s first supermarket, but “credits the modern supermarket – ‘the huge self-service, cash-and-carry, one-stop outlet with small markup, large volume, and the all-important parking lot’ – to the Great Depression and a man named Michael Cullen.” Similarly, Supermarket News noted that "[a]lthough there is some disagreement, the overwhelming majority opinion is that the supermarket was invented by Michael Cullen." 
King Kullen was founded by Michael J. Cullen, a former Kroger employee who devised the concept of the modern supermarket. While the branch manager of the Herrin, Illinois branch of the Kroger Grocery & Baking Company stores, managing 94 small stores, Cullen wrote a six-page letter to John Bonham, a Kroger vice-president, proposing a new type of food store with a focus on low prices, cash sales, and without delivery service, in larger stores (at low rents) with ample parking. He described what he envisioned as “monstrous stores, size of some to be about forty feet wide and hundred and thirty to a hundred and sixty feet deep, and they ought to be located one to three blocks off the high rent district with plenty of parking space, and some to be operated as a semi-self-service store – twenty percent service and eighty percent self-service.” In his proposal, Cullen suggested that this new type of store could achieve 10 times the volume and profits of the average Kroger or A&P, making Kroger "the greatest chain grocery concern on the face of the earth."
After Cullen's letter went unanswered, he resigned and moved with his wife Nan and their children to Long Island, where he launched his concept. Cullen leased a vacant garage at 171-06 Jamaica Avenue, on the corner of 171st Street and Jamaica Avenue in Jamaica (Queens), near a busy shopping district. The store, named "King Kullen", opened on August 4, 1930. After an over 80 year presence in New York City, King Kullen left that market in 2011 with the sale of its 3 remaining New York City stores in Eltingville, Graniteville, and Greenridge on Staten Island.
Very soon after opening the first King Kullen, customers came from 100 miles away to shop there. The first store was ten times larger than the Atlantic & Pacific Tea Company stores in the market. The second store was opened a few miles away from the first store, on Jamaica Avenue in Bellaire, Queens. Within two years of opening, the company operated eight stores with sales totaling $2.9 million. The early stores were 5200 to 6400 square feet big. Within 6 years of opening, King Kullen had 15 locations. By 1952, King Kullen had 30 stores, ranging in size from 10,000 to 15,000 square feet.
Cullen died at Flushing Hospital on April 24, 1936 at the age of 52, from peritonitis following an appendectomy. His widow Nan took over King Kullen, becoming Chairman of the Board. She was joined by her sons James A. Cullen (then 24) and John B. Cullen (then 15).
