[3] The Taggart Baking Company of Indianapolis, Indiana, began producing Wonder Bread that debuted on May 21, 1921,[4] following a blind promotion with ads that only stated a "Wonder" was coming on that date.

The brand was named by vice president for merchandising development Elmer Cline, who was inspired by the International Balloon Race at the Indianapolis Motor Speedway.

[2] The logo was designed by commercial artist Drew Miller while he was on staff at a Chicago ad agency.

[10] Unsliced bread returned for a period during World War II due to an industry-wide slicing suspension in 1943.

The company sponsored Howdy Doody, with host Buffalo Bob Smith telling the audience, "Wonder Bread builds strong bodies 8 ways" referring to the number of added nutrients.

[14] By the 1960s, Wonder Bread was advertised with the slogan "Helps build strong bodies 12 ways," with a list of health claims.

[18] On August 28, 2007, Interstate Bakeries announced it would soon end production of Wonder Bread in the Southern California market, leading to a loss of 1,300 jobs.

Wonder 100% Whole Wheat (16 oz variety) qualified for the Women, Infants and Children or WIC program in most states.

[citation needed] On November 16, 2012, Hostess Brands (Old HB) filed a motion in United States Bankruptcy Court for the Southern District of New York seeking permission to close its business and sell its assets under Chapter 11.

[24] The company closed plants and began liquidation proceedings, temporarily ending production of Wonder Bread in the states.

At the end of that year, it was folded into Consolidated Bakeries Limited, controlled by Ogilvie Flour Mills.

Between 2000 and 2022, Weston Foods added a number of new Wonder products to the brand's line-up, many of which were designed to appeal to parents and their concern for their children's nutritional needs.
