America met the croissant frozen. Sara Lee brought a frozen croissant to the United States in 1981, and it soon outsold the company's pound cakes.
The chains were not far behind. By 1984 a New York Times article could announce that the Americanization of the croissant had begun, and Burger King's Croissan'wich was already turning up in California newspaper advertising, in a Press Democrat notice that offered flame-broiled burgers, a salad bar and a drive-through in the same breath.
The holiday came along without a signature. Its earliest mention anywhere in HathiTrust's collection sits in a 2008 volume of a Colorado Springs monthly for activity professionals in retirement communities.
