History of Breakfast Cereal Timeline

The Western Health Reform Institute was established in Battle Creek by the Seventh-day Adventists to offer their natural remedies for illness. It would become the birthplace of ready-to-eat cereal innovation.

Son of an Adventist factory owner in Battle Creek, John Harvey Kellogg (1851–1943) was encouraged by his church to train in medicine at Bellevue Hospital Medical College in New York City in 1875.

After graduating from Bellevue Hospital Medical College, Kellogg became medical superintendent at the Western Health Reform Institute in Battle Creek, where he promoted healthful vegetarian foods including new cereals.

In 1891 Kellogg acquired a patent and then in 1895 launched the Cornflakes brand, which overnight captured a national market and cemented Battle Creek as the cereal capital of America.

In 1897 (or 1898), C. W. Post introduced Grape-nuts, the concentrated cereal with a nutty flavor containing neither grapes nor nuts, one of the most enduring cereal brands.

Will Keith Kellogg (1860–1951) worked for his brother John Harvey for many years until, in 1906, he broke away, bought the rights to Cornflakes, and set up the Kellogg Toasted Corn Flake Company.

After C. W. Post's death, his company acquired the Jell-O company in 1925, Baker's Chocolate in 1927, Maxwell House coffee in 1928, and Birdseye frozen foods in 1929, building a food conglomerate.

In 1929, following its string of acquisitions, the company changed its name to General Foods, becoming one of the largest packaged food companies in America.

In 1944, General Foods launched a marketing campaign for Grape Nuts focusing on the nutritional importance of breakfast, helping entrench cereal as an essential morning meal.

In 1985, Philip Morris Tobacco Company bought General Foods for $5.6 billion (equivalent to $16.8 billion today) and merged it with its Kraft division, ending General Foods' independence.

In 1921, James Ford Bell, president of a Minneapolis wheat milling firm, began experimenting with rolled wheat flakes, leading to the creation of Wheaties.

After World War II-era growth, General Mills—who had entered the market in 1924 with Wheaties—became one of the big breakfast cereal companies increasingly targeting children.

By 1925, Wheaties had become known as the 'Breakfast of Champions', building its identity through sports endorsements that connected the cereal with athletic excellence.

In 1928, four milling companies consolidated as the General Mills Company in Minneapolis, creating a major competitor in the breakfast cereal and flour industries.

By 1941 Wheaties had won 12% of the cereal market, establishing General Mills as a dominant force in the ready-to-eat cereal business.

Ranger Joe, the first pre-sweetened breakfast cereal made of sugar-coated puffed wheat or rice, was introduced in the US in 1939, opening the era of heavily sweetened children's cereals.

After World War II, the big breakfast cereal companies—including General Mills and Kellogg's—increasingly started to target children, using mascots, cartoons, and advertising to drive sales.

Kellogg's Sugar Smacks, created in 1953, had 56% sugar by weight, exemplifying the postwar trend of highly sweetened cereals aimed squarely at children.

Between 1970 and 1998, the number of different types of breakfast cereals in the United States more than doubled, from about 160 to around 340 varieties.

Over 2016 to 2017, Americans purchased 3.1 billion boxes of cereal, mostly as ready-to-eat cold cereal, showing the enduring popularity of the category.

A January 2025 study in the American Journal of Preventive Medicine examined cereal purchases from 77,000 American households over nine years alongside Nielsen ratings data on advertising exposure.
